NOTE
This manual refers to the use of the pistol by civilian users. Instructions for law
enforcement use may differ from what is described in this manual.

Throughout this instruction manual, position designations such as "left," "right,"
"forward," "rear," and so on, are referenced to a pistol held in a normal firing position.
In other words, pointed away from the shooter, barrel in a generally horizontal
direction, and with the grip of the pistol pointing downwards.

Explanations in this manual are based on right hand operation. Left-handed users
should operate vice versa.

DISCLAIMER OF LIABILITY
The first concern when handling any firearm is safety. The failure to do so may result
in property damage, serious bodily injury or even death. WALTHER specifically
disclaims any and all liability from anyone arising out of the use of this firearm and its
accessory. Under no circumstances shall WALTHER be responsible for incidental or
consequential damages with respect to economic loss or injury to person or property
due to negligence, improper use, failure to following instructions in this manual,
unsafe handling, failure to maintain the pistol, unauthorized replacement of parts,
disregard of statutory rules or laws or any other modification to the pistol.

1 YOUR SAFETY RESPONSIBILITIES

SAFETY IS YOUR NUMBER ONE RESPONSIBILITY!!!!
At home, in the field, at the range, or anywhere, the first concern of every firearm

owner should be safety. Apply the following safety rules in every situation, with any
kind of firearm. If you feel uncertain about any operational aspects of your handgun,
please contact WALTHER at 1-800-372-6454 before proceeding with its operation.

WARNING: YOU MUST FOLLOW ALL OF THESE SAFETY RULES TO
ENSURE THE SAFE USE OF YOUR FIREARM. THE FAILURE TO
FOLLOW THESE BASIC FIREARM SAFETY RULES MAY RESULT IN AN
UNINTENDED DISCHARGE WHICH COULD CAUSE SERIOUS
PERSONAL INJURY OR DEATH TO YOU OR OTHERS.

• ALWAYS KEEP YOUR FIREARM POINTED IN A SAFE DIRECTION. Never
point a firearm at anyone or anything you do not intend to shoot, whether or
not it is loaded. This is particularly important when loading, unloading, or field
stripping the gun. ALWAYS control the direction of the firearm.

• ALWAYS TREAT EVERY FIREARM AS IF IT IS LOADED AND WILL FIRE
IF THE TRIGGER IS PULLED. Do not take anyone’s word that the firearm is
unloaded – always check for yourself. Never pass your firearm to another
person until the cylinder or action is open and you visually check that it is
unloaded. Keep your firearm unloaded and safely stored when not in use.

• NEVER PLACE YOUR FINGER INSIDE THE TRIGGER GUARD OR ON
THE TRIGGER UNLESS YOU INTEND TO FIRE. Ensure that other objects
do not touch the trigger.

• ALWAYS BE SURE OF YOUR TARGET AND WHAT IS BEYOND IT.
Always be sure of where the bullet will strike and shoot only where there is a
safe back stop free of obstructions, water or other surfaces which can cause
ricochets. Do not fire into the sky.

• NEVER CROSS OBSTACLES SUCH AS FENCES OR STREAMS WITH A
LOADED FIREARM.

• SAFE GUN HANDLING IS YOUR PERSONAL RESPONSIBILITY at all
times. Firearms are dangerous and can cause serious injury or death if they
are misused or used inappropriately. Safety must be the prime consideration
of anyone who owns or handles firearms.
Accidents are the result of violating the rules of safe gun handling and
common sense. Firearm safety training is available. Contact your dealer, law
enforcement agency, local sportsman’s club, etc. for availability.

4

YOUR SAFETY RESPONSIBILITIES CONT’D.

• YOU ARE RESPONSIBLE FOR THE FIREARM AT ALL TIMES.
In owning a firearm, you must undertake full-time responsibility for your
firearm’s safety and security. You must protect yourself and all others against
injury or death from misuse of the firearm 24 hours a day.

• FIREARM SECURITY IS YOUR RESPONSIBILITY.
You must secure firearms safely from children and/or unauthorized users.
Your firearm should always be kept unloaded and locked when not in use. A
lock has been provided for this purpose. Never assume that the use of this
lock is sufficient to safely secure your firearm. You must always evaluate your
personal situation and employ the security system(s) that meets your needs
and prevents children and unauthorized users from gaining access to your
firearm.

• APPROPRIATE USE FOR YOUR FIREARM MEANS USING YOUR
FIREARM FOR LEGAL PURPOSES.
For example - target shooting and lawful resistance of deadly criminal force. It
is your responsibility to ensure that you are in compliance with all applicable
laws and ordinances regarding the use of your firearm.

• NEVER RELY ON MECHANICAL FEATURES ALONE. Only your safe gun­handling habits will ensure the safe use of your firearm. This is your
responsibility.

• ALWAYS SAFELY STORE AND SECURE YOUR FIREARM.
Safe and secure storage of your firearm is one of your most important
responsibilities. It is a full-time responsibility. You must always secure your
firearm and ammunition separately so that they are not accessible to children
and/or other unauthorized persons.

• NEVER KEEP AMMUNITION IN THE SAME LOCATION AS THE HANDGUN.
Store each in a separate and secure place.

• ALWAYS WEAR EYE AND EAR PROTECTORS THAT ARE SPECIFIED FOR
FIREARM USE every time you discharge your firearm. Make sure others in
the vicinity of where you will be shooting do so as well.

• NEVER USE ALCOHOL OR DRUGS BEFORE OR WHILE SHOOTING.
Do not use your firearm if you are on any medication which impairs, even
slightly, your mental or physical ability.

• ALWAYS HAVE ADEQUATE VENTILATION.
Discharging firearms in poorly ventilated areas, cleaning firearms, or handling
ammunition may result in exposure to lead and other substances known to
cause birth defects, reproductive harm, and other serious physical injury.
Review the warnings and labels for all ammunition and cleaning products
carefully. Wash hands thoroughly after exposure.

5

YOUR SAFETY RESPONSIBILITIES CONT’D.

• BEFORE HANDLING ANY FIREARM, UNDERSTAND ITS OPERATION.
Not all firearms are the same. Familiarize yourself with the mechanical
features of any firearm you intend to use. If you feel uncertain about any
operational aspects of your handgun, please contact WALTHER at
1-800-372-6454 before proceeding with its operation.

• NEVER ALLOW A FIREARM TO BE USED BY INDIVIDUALS WHO DO NOT
UNDERSTAND ITS SAFE OPERATION OR HAVE NOT READ THESE
FIREARM SAFETY RULES.

• ALWAYS USE THE CORRECT AMMUNITION FOR YOUR PARTICULAR
FIREARM as indicated by the marking on the barrel. Never use non-standard,
reloaded, or “handloaded” ammunition which has not been subjected to
internal ballistic pressure testing.

• BE SURE ALL ACCESSORIES, SUCH AS HOLSTERS AND GRIPS, ARE
COMPATIBLE with the handgun and that the accessories do not interfere with
safe operation.

• NEVER DISASSEMBLE YOUR HANDGUN beyond the field stripping
procedure outlined in this manual. Improper disassembly or reassembly of
your handgun may be dangerous and can lead to serious injury or death.

• NEVER MANIPULATE, ADJUST OR CHANGE ANY OF THE INTERNAL
COMPONENTS OF YOUR FIREARM including the firing pin, sear, or
drawbar.
Improper manipulation of any internal component may affect the safety and
reliability of your firearm and may cause serious injury or death.

• NEVER ALLOW ANY ALTERATION OR REPLACEMENT OF PARTS IN
YOUR WALTHER FIREARM UNLESS PERFORMED BY A QUALIFIED
GUNSMITH using genuine WALTHER parts. If you do otherwise, improper
functioning of your firearm may occur and serious injury or death may result.

WARNING: SAFE USE OF A FIREARM IS YOUR PERSONAL
RESPONSIBILITY AND THE FAILURE TO FOLLOW ALL OF THESE BASIC
SAFETY RULES MAY RESULT IN SEVERE PERSONAL INJURY OR
DEATH TO YOU OR OTHERS.
YOU ARE THE MOST IMPORTANT SAFETY DEVICE WHEN IT COMES
TO THE USE OF YOUR FIREARM AND WALTHER WILL NOT BE
RESPONSIBLE FOR ANY PERSONAL INJURY, DEATH OR PROPERTY
DAMAGE THAT RESULTS FROM:

6

(1) THE CRIMINAL OR NEGLIGENT USE OF THIS HANDGUN;
(2) A DISREGARD OF THESE SAFETY INSTRUCTIONS AND

WARNINGS;
(3) IMPROPER OR CARELESS HANDLING OF THIS FIREARM;
(4) THE USE OF NON-STANDARD, DEFECTIVE, IMPROPER OR

RELOADED AMMUNITION; OR
(5) IMPROPER OR NEGLIGENT MODIFICATIONS OR REPAIRS TO THE

HANDGUN.

1.1 SAFE STORAGE & TRANSPORTATION

WARNING: FIREARMS ARE DANGEROUS WHEN USED AND STORED
IMPROPERLY THEY POSE A RISK OF SERIOUS OR FATAL INJURIES.
FIREARMS CAN BE ESPECIALLY DANGEROUS TO CHILDREN WHEN
THEY ARE STORED IN AN IRRESPONSIBLE AND UNSAFE MANNER.
FOR YOUR SAFETY AND THE SAFETY OF OTHERS, IT IS IMPERATIVE
THAT YOU KEEP YOUR FIREARM LOCKED AND UNLOADED IN A
SECURE PLACE.
THE AMMUNITION SHOULD BE STORED IN A SEPARATE, SECURE
LOCATION WHEN IT IS NOT IN USE.
SAFE AND SECURE STORAGE OF YOUR FIREARM IS ONE OF THE
MOST IMPORTANT RULES OF FIREARM SAFETY.
YOUR FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS
INJURY OR DEATH TO YOU OR OTHERS.

• ALWAYS SECURE YOUR FIREARM IN A MANNER THAT WILL PREVENT
UNAUTHORIZED ACCESS.

• Whenever your firearm is not in use, keep it unloaded and locked. Your
safety and the safety of others requires that you always secure and store
your firearm in a manner that will prevent unauthorized access. Never leave
a firearm unattended unless it is locked, unloaded and secured.

• ALWAYS USE THE LOCK PROVIDED BY WALTHER TO SECURE YOUR
FIREARM.
Please read and follow the instructions packaged separately for the use of
this lock. A lock, when properly used, can be an effective tool in preventing
unauthorized access to your firearm. There are other alternative locks and
safe storage containers available in the marketplace which may also be
appropriate for your particular needs. Consult your local gunshop, hardware
store, or local police department for guidance on the variety of other safe
storage devices or practices which may be appropriate for your particular
needs. By purchasing this firearm you have accepted the responsibility of
safely securing the firearm at all times and preventing its unauthorized use.
Never assume that the use of this lock alone is sufficient to safely secure
your firearm. It is your personal responsibility to select and use whatever
measures or practices that will enable you to be absolutely certain that your
firearm is secure at all times.

WARNING: NEVER LOCK A LOADED FIREARM
AND NEVER LOAD A LOCKED FIREARM!!

• ALWAYS STORE YOUR FIREARM AND AMMUNITION SEPARATELY so
that they are not accessible to children or other unauthorized persons. Safe
and secure storage of your firearm and ammunition are your responsibility. It
is a full-time responsibility.

7

SAFE STORAGE & TRANSPORTATION CONT’D.

• NEVER ASSUME THAT A “HIDING” PLACE IS A SECURE STORAGE
METHOD.
Others may be aware of your storage location or come upon it by chance. It
is your personal responsibility to use common sense when storing your
firearm and ammunition and to always make sure they are not accessible to
children or other unauthorized persons.

• NEVER TRANSPORT A LOADED FIREARM.
When transporting your firearm, be sure it is unloaded and locked. Safe and
secure transportation of your firearm is your responsibility.

• ALWAYS FOLLOW THE LAW!
Many jurisdictions have laws that make it a crime to keep a firearm unlocked
and in an area accessible to children or others. Keeping a firearm locked and
unloaded when not in use is not only common sense safety practice... IT IS
THE LAW. You must be familiar with all local, state, and federal laws
regarding the safe storage and transportation of your firearm. Failure to know
and follow the law may result in unauthorized access or use of your firearm
by another. Obey all laws relating to the storage and transportation of
firearms. Your local police department or gunshop can furnish you with
available information on storing and/or transporting a firearm safely and
legally.

• YOUR FIREARM IS YOUR RESPONSIBILITY.
You must prevent your firearm from being stolen or from being used by
untrained or unqualified individuals. Keep it locked, unloaded and secured
when not in use.

2.3 Ammunition

WARNING: NEVER USE AMMUNITION NOT SPECIFICALLY DESIGNATED
FOR USE IN YOUR WEAPON. FAILURE TO USE THE SPECIFIC
CARTRIDGE INTENDED FOR USE IN THE P99 PISTOL MAY CAUSE THE

PISTOL TO JAM, FAIL TO FIRE OR EVEN GENERATE EXCESSIVE GAS
PRESSURE WHICH CAN DAMAGE OR DESTROY THE PISTOL, CAUSE
PERSONAL INJURY, DEATH OR PROPERTY DAMAGE.

Locate the caliber designation marked on the
pistol. This information indicates the ammunition
that must be used in this pistol (see 2.3 Figure 1).
You are responsible for selecting ammunition that
meets industry standards and is appropriate in
type and caliber for this firearm.

Never use a cartridge not specifically designated
for use in your firearm. Pressure from the wrong
type of ammunition may exceed the capability of

2.3 Fig. 1

your firearm and may damage or even rupture
your firearm.

Never mix ammunition.
In some cases, a round of ammunition not specified on your handgun may fit into the

chamber. Firing ammunition not specified on your handgun may cause it to rupture
and cause serious injury or death to you or others.

Always inspect your ammunition before using it. Never use dirty, corroded or
damaged ammunition which can lead to a burst cartridge which may cause damage
to the handgun and personal injury or death.

Use only commercially manufactured ammunition with internal ballistic pressures
which are in strict accordance with the specifications of the Sporting Arms and
Ammunition Manufacturers’ Institute (SAAMI). If you are uncertain, contact your
ammunition supplier for verification.

WARNING: NEVER USE NON-STANDARD, RELOADED OR
“HANDLOADED” AMMUNITION WHICH HAS NOT BEEN SUBJECTED TO
INTERNAL BALLISTIC PRESSURE TESTING.
RELOADED OR HANDLOADED AMMUNITION, MAY HAVE MANY
MANUFACTURING AND QUALITY VARIABLES (SUCH AS THE TYPE AND
AMOUNT OF GUN POWDER).
ANY AMMUNITION THAT IS IMPROPERLY MANUFACTURED, EVEN IN
THE SLIGHTEST DEGREE, MAY FAIL TO FIRE OR MAY GENERATE
EXCESSIVE INTERNAL PRESSURES WHICH CAN DAMAGE OR EVEN
RUPTURE THE FIREARM, CAUSING PERSONAL INJURY OR DEATH TO
THE SHOOTER OR THOSE IN THE IMMEDIATE VICINITY.

A firearm and ammunition are a system and must work together. Their performance
is closely related. There are different types of ammunition for different types of
firearms. Your firearm has been designed for ammunition of a specific type and a
specific caliber. It is important to select the proper ammunition for your firearm.

9

Different combinations of bullet velocity, bullet weight and firearm weight can have
major impact on felt recoil; high felt recoil can be uncomfortable to some shooters.

For example:

• Gun Weight: lower gun weight increases felt recoil.

• Bullet Weight: higher bullet weight increases felt recoil.

• Bullet Velocity: higher bullet velocity increases felt recoil.

To acclimate yourself to higher levels of felt recoil, consider the following:

• Use a firm two-hand hold on the grip when firing.

• Always start your shooting experience with the lowest bullet velocity and

lowest bullet weight available for your firearm.

• Ask your firearm dealer to suggest the lowest power, lowest velocity, lightest
bullet weight for your firearm.

• You can also consider changing your firearm’s grip configuration/composition
to better fit your hand’s specific size and shape.

“Plus-P” (+P) ammunition generates pressures in excess of the pressures associated
with standard ammunition. Such pressures may affect the wear characteristics of
your P99 pistol.

“Plus-P-Plus” (+P+) ammunition must not be used in WALTHER firearms. This
marking on the ammunition designates that it exceeds established industry
standards, but the designation does not represent defined pressure limits and
therefore such ammunition may vary significantly as to the pressures generated.

Some brands of ammunition may cause difficulty in extracting spent cartridge cases
from the chamber. If this situation occurs, thoroughly clean the chamber with solvent.
If this condition persists, we recommend changing to another brand of ammunition.

2.4.2 Striker Status Indicator
The P99 has a cocking indicator in the rear of the slide. The pistol uses an internal

striker with a tip that protrudes out of the slide end cap when the striker is cocked.

• In the de-cocked state, the tip can be neither seen nor felt (2.6 Fig. 2, left side).

• The tip protrudes from the rear of the slide when the pistol is cocked

(2.4 Fig. 2, middle).

• The tip is approximately .04”
(1 mm) inside the slide end
cap on cocked P99 QA
(2.4 Fig. 2, right side).
It can be seen, but not felt.

3 PREPARATION FOR FIRING

WARNING: THE FAILURE TO FOLLOW THESE
FIREARM SAFETY REQUIREMENTS MAY CAUSE
SERIOUS PERSONAL INJURY OR DEATH TO YOU
OR OTHERS.

• ALWAYS TREAT ALL HANDGUNS AS IF THEY ARE LOADED.

• ALWAYS BE SURE THAT ALL ACTIONS OF FIREARMS ARE OPEN, THAT

CHAMBERS ARE CLEAR OF CARTRIDGES, MAGAZINES ARE
REMOVED, AND THAT FIREARMS ARE POINTING IN A SAFE
DIRECTION.

• ALWAYS KEEP FINGERS AND OTHER PARTS OF YOUR BODY AWAY
FROM THE MUZZLE, AND AWAY FROM THE PISTOL SLIDE AND
EJECTION PORT.

• ALWAYS WEAR ADEQUATE AND PROPER EAR PROTECTORS
SPECIFIED FOR FIREARM USE to prevent permanent damage to your
hearing. Make sure others who are nearby are wearing ear protection as
well.

• ALWAYS WEAR SAFETY GLASSES SPECIFIED FOR FIREARM USE,
whether indoors or out. Safety glasses should protect your eyes from the
firing flash and particles associated with the discharge of ammunition. Failure
to do so creates a risk of personal injury from particle or debris spitting or
ricochets.

• ALWAYS BE ALERT AND ALWAYS FOLLOW THE SAFETY
INSTRUCTIONS OF THE RANGE OFFICER.
Never shoot if you are tired, cold or impaired in any way.

13

• ALWAYS BE AWARE OF OTHER PEOPLE so that persons cannot
accidentally walk into the line of fire.

• THE SHOOTER (AND ALL OTHERS IN THE SHOOTING AREA) MUST
ALWAYS BE IN A POSITION THAT IS OUT OF THE LINE OF FIRE and are
not within an area where they may be struck by ricochets, particles spitting
from a revolver, or by ejected cases from other types of firearms.

• NEVER SHOOT AT HARD SURFACES, WATER OR UP INTO THE SKY.
Always select a place to shoot that has a safe backstop and is free from
obstructions and water surfaces which cause ricochets.

• NEVER USE ALCOHOL OR DRUGS BEFORE OR WHILE SHOOTING.

3.1 Inspecting the Pistol

• When you inspect the pistol, you should first check
to ensure that it is unloaded. To do this, grasp the
grip of the frame with your finger off the trigger and
outside the trigger guard, point the muzzle in a safe
direction, depress the magazine release and remove
the magazine (3.1 Fig. 1).

• Grasp the serrated sides of the slide from the rear
with the thumb and fingers as shown in 3.1 Fig. 2,
and briskly draw the slide fully rearward in order to
extract any cartridge from the chamber and clear it
from the pistol.
Do not obstruct the ejection port because doing so
can interfere with the proper ejection of a cartridge.

• Lock the slide in the open position by allowing the
slide to move slightly forward from the rearmost
position while pressing upward on the slide stop
(3.1 Fig. 3).

• Check the chamber to verify that it is unloaded and
check the bore visually that it is clean, dry, and free
from any obstructions (3.1 Fig. 4).

3.1 Fig. 1

3.1 Fig. 2

3.1 Fig. 3

You must follow this procedure every time the P99
leaves your hand, is cleaned, handed to you or another
person, transported or stored.

WARNING: NEVER RELY ON MECHANICAL
FEATURES ALONE. PROPER HANDLING OF
THE PISTOL WILL ENSURE THE SAFETY OF

YOUR FIREARM. FIREARM SAFETY IS
ALWAYS YOUR RESPONSIBILITY.

14

3.1 Fig. 4

3.2 Loading

• Do not load the pistol until you have read and fully understand this manual.

• Do not load the pistol until you are ready to use it. Keep your finger off the trigger

and outside the trigger guard until you are ready to fire.

• Never load your pistol until you are sure of your target, what is beyond it and are
fully prepared to fire.

• WALTHER has provided you with a magazine designed to operate in your specific
model of pistol. While your magazine may be able to be inserted into another
model pistol, it will only function properly in the specific model for which it was
designed.
Do not interchange magazines from one model pistol to another model pistol.

• Follow instructions in this manual and any other specific instructions which may be
marked onto, or accompany, a magazine. Failure to use the particular type of
WALTHER magazine specified for your model and caliber of pistol may result in a
malfunction.

3.2.1 Magazine

When the magazine is removed from the magazine well in the grip, the number of
rounds can be seen in the witness holes.

With the proper adapter, Full Size magazines may
be used on a P99 Compact. The adapter is an
accessory item (3.2 Fig. 1).
The adapter changes the grip of a Compact to a
more comfortable one, and allows for a higher
magazine capacity.

CAUTION: To avoid damage to the ejector,
use the adapter if a Full Size magazine is
to be used in a P99 Compact.

3.2.2 Loading the Magazine

Do not attempt to load the magazine with more than the specified number of
cartridges because doing so may cause a failure to feed a round of
ammunition into the chamber. Do not use excessive force when loading the
magazine, as this may damage the magazine. Damaged or defective
magazines cause malfunctions and may cause improper functioning of the
pistol.

Load the magazine by pressing a cartridge
base (rear of cartridge) downward on the
forward portion of the magazine follower (or
downward on the case of a previously loaded
cartridge) and sliding the cartridge fully under
the lips of the magazine until the cartridge
base is against the rear wall of the magazine.
Repeat the procedure for the number of
cartridges you wish to load, up to the
magazine capacity (3.2 Fig. 2).

3.2 Fig. 1

3.2 Fig. 2

15

Loading may be made easier with the aid of the WALTHER Magazine Loader:
Put the magazine loader with its long wall oriented to the rear on top of the magazine
(3.2 Fig. 3). Press down the magazine loader and insert a cartridge with your other
hand (3.2 Fig. 4). Let the magazine loader go up again. Push in the cartridge
completely with your hand. Repeat the procedure for the number of cartridges you
wish to load, up to the magazine capacity.

3.2 Fig. 4 3.2 Fig. 3

3.2.3 Loading the Pistol

• Inspect the pistol as shown in section 3.1.

• Grasp the pistol with your finger off the trigger and outside the trigger guard, point

the muzzle in a safe direction. Insert the loaded magazine into the magazine well
of the pistol until it is locked in place.
To make sure that the magazine is fully and securely inserted, try pulling down on
the exposed portion of the magazine floorplate. It should not move.

WARNING: DO NOT USE EXCESSIVE UPWARD FORCE WHEN
INSERTING A LOADED MAGAZINE INTO THE PISTOL. EXCESSIVE
UPWARD FORCE COULD CAUSE THE SLIDE TO MOVE FORWARD,
CHAMBERING A ROUND AND MAKING THE PISTOL READY TO FIRE.

• Pull the slide fully to the rear and let go allowing it to move fully forward.
WARNING: IF THE CARTRIDGE FAILS TO STRIP FROM THE MAGAZINE

OR FULLY SEAT INTO THE CHAMBER, IMMEDIATELY STOP THE
LOADING PROCESS. REMOVE THE MAGAZINE, LOCK THE SLIDE OPEN
AND VERIFY THAT THE CHAMBER IS EMPTY. REFER TO THE
“INSPECTING THE PISTOL” SECTION OF THIS MANUAL.

• After the slide is closed, press down the decocker (P99 AS only). Doing so resets

the trigger action from Single Action to Double Action mode.

WARNING: ALWAYS LOAD A ROUND INTO THE CHAMBER BY FEEDING
IT FROM THE MAGAZINE. NEVER ATTEMPT TO LOAD THE PISTOL BY
INSERTING A ROUND INTO THE CHAMBER VIA THE OPEN EJECTION
PORT. FAILURE TO FOLLOW THIS WARNING MAY RESULT IN SEVERE
INJURY OR DEATH TO YOU OR OTHERS.

16

CAUTION

THE PISTOL IS NOW LOADED AND READY TO FIRE.
THE PISTOL AND ITS MAGAZINE ARE NOW LOADED AND WILL FIRE

WHEN THE TRIGGER IS SQUEEZED. REMEMBER TO KEEP THE MUZZLE
POINTED IN A SAFE DIRECTION UNDER ALL CONDITIONS AND ALWAYS
KEEP YOUR FINGER OR ANY OTHER OBJECT OFF THE TRIGGER AND
OUTSIDE THE TRIGGER GUARD UNTIL YOU DECIDE TO FIRE THE
PISTOL.
NEVER LEAVE A LOADED FIREARM UNATTENDED OR OUT OF YOUR
DIRECT CONTROL.

• If you wish to restore the magazine in your pistol to its full capacity, depress the
magazine release and remove the magazine from the pistol. Remember that there
is a round in the chamber; therefore, the weapon should be holstered or safely
secured during this process without touching the trigger. Load one cartridge into
the magazine to replace the one which was chambered when you allowed the
slide to carry forward.

• Re-insert the loaded magazine into the magazine well of the pistol until it is locked
in place. To make sure that the magazine is again fully and securely inserted,
apply some removal pressure to the exposed portion of the magazine butt plate.

• Your pistol and its magazine are now fully loaded and will fire when the trigger is
pulled. Remember to keep your pistol pointed in a safe direction under all
conditions and always keep your finger or any other object off the trigger and
outside the trigger guard until you have made the commitment to fire the handgun.
Never leave a loaded firearm out of your direct control.

WARNING: AFTER INSERTING A MAGAZINE, ALWAYS TEST TO MAKE
SURE IT IS LOCKED IN PLACE BY APPLYING SOME REMOVAL
PRESSURE TO THE EXPOSED PORTION OF THE BUTT PLATE.

WARNING: THE P99 IS NOT EQUIPPED WITH A MAGAZINE
DISCONNECT FEATURE. THE P99 WILL FIRE WITH THE MAGAZINE
REMOVED FROM THE PISTOL.

3.3 Decocker (P99 AS)

The decocker offers a safe way of de-cocking the
P99 AS. The decocker is routinely used to de-cock the
striker. De-cock the P99 AS after loading, before
holstering and prior to disassembly.
Press the decocker downwards into the slide until the
striker is audibly and visually de-cocked (3.3 Fig. 1).
If you find that it is difficult or cumbersome to manipulate
the decocker using your shooting hand’s thumb, or if

3.3 Fig. 1

you are left-handed, you should use the thumb of your non-shooting hand to do so.

Always point the pistol in a safe direction during de-cocking.

Always de-cock the P99 AS before holstering. The de-cocked pistol remains
ready for service using the Double Action trigger

WARNING: Pulling the slide rearward will cock the striker again.

3.4 Firing the P99 DAO, P99 QA, and P99 AS

3.4.1 Firing, General

WARNING: ALWAYS KEEP THE MUZZLE POINTED IN A SAFE
DIRECTION.

WARNING: WEAR EYE AND EAR PROTECTION SPECIFIED FOR
FIREARM USE EVERY TIME YOU DISCHARGE YOUR FIREARM. MAKE
SURE OTHERS IN THE VICINITY OF WHERE YOU WILL BE SHOOTING
DO SO AS WELL.

WARNING: “STAGING” THE TRIGGER VIOLATES A BASIC RULE OF
FIREARM SAFETY WHICH WARNS YOU TO KEEP YOUR FINGER OUT
OF THE TRIGGER GUARD UNTIL YOU HAVE MADE THE COMMITMENT
TO FIRE. “STAGING” CREATES A SERIOUS RISK OF PERSONAL
INJURY OR DEATH SINCE IT MAY LEAD TO AN UNINTENTIONAL
DISCHARGE.

• It has come to our attention that some users of WALTHER handguns may
stage the trigger in anticipation of firing a shot. Staging is the act of pulling
the trigger rearward toward – stopping just short of – the point where the
handgun fires. Such manipulation of the trigger can reduce the user’s control
of the handgun and can result in an unintentional discharge. Furthermore if
the user decides not to fire, release of the trigger from a position close to the
firing point in the staging process could result in an unintentional discharge.

• How a handgun is gripped affects recoil and trigger control. Always ensure
that you maintain a firm grip and proper alignment of the pistol. The design of
the P99 frame offers a high degree of control permitting the shooter to obtain
an elevated grip closer to the pistol’s bore axis.

• Keep the muzzle pointed in a safe direction and your finger outside the
trigger guard until you are ready to fire.

• With a firm grip, allow your finger to be placed squarely across the face of the
trigger. Squeeze the trigger fully to the rear.

As the trigger is drawn fully to the rear, the striker is released, striking the
cartridge primer. Upon firing, the slide moves rearward thereby extracting
and ejecting the spent cartridge case. The slide then returns forward feeding
the next cartridge from the magazine into the chamber.

• After firing, you must allow the trigger to move fully forward before you can
fire the next shot. Failure to do so will prevent the lockwork from fully cycling
and will prevent you from being able to fire the next shot. Keep your finger off
the trigger and outside the trigger guard until you are ready to fire again.
This sequence can be repeated until the last round has been fired.

• Once the last round has been fired, the magazine follower exerts upward
pressure on the slide stop causing it to engage the slide and to hold it in the
“open” position.

18

WARNING: AFTER INSERTING A MAGAZINE, ALWAYS TEST TO MAKE
SURE IT IS LOCKED IN PLACE BY APPLYING SOME REMOVAL
PRESSURE TO THE EXPOSED PORTION OF THE BUTT PLATE.

WARNING: UPON FIRING THE PISTOL OR RELEASING THE SLIDE
FROM THE SLIDE STOP, THE SLIDE MOVES REARWARD OR
FORWARD WITH SIGNIFICANT FORCE AND SPEED.
TO AVOID INJURY, BE SURE NO PART OF YOUR BODY IS IN THE PATH
OF THE SLIDE’S TRAVEL.

3.4.2 Firing the P99 DAO
Firing is done as described above. After firing you must allow the trigger to move fully

forward before you can fire the next shot. Failure to do so will prevent the lockwork
from fully cycling, and will prevent the firing of the next shot.

This sequence can be repeated until the last round has been fired. Trigger pull and
trigger travel is the same from the first to the last round.

If a cartridge fails to fire, the trigger may be squeezed again to fire the round.

3.4.3 Firing the P99 QA
Firing is done as described in section 3.4.1 “Firing, General”. After firing you must

allow the trigger to move forward before you can fire the next shot. Failure to do so
will prevent the lockwork from fully cycling, and will prevent the firing of the next shot.

This sequence can be repeated until the last round has been fired. Trigger pull and
trigger travel is the same from the first to the last round.

3.4.4 Firing the P99 AS
With the striker de-cocked, the first round will be fired in Double Action mode and

subsequent shots will be fired in Single Action mode until you de-cock the P99 AS
again.

3.4.4.1 P99 AS, Double Action Trigger

• Load the pistol and de-cock it. Keep the muzzle pointed in a safe direction. Keep
your finger off the trigger and outside the trigger guard until you are ready to fire.

CAUTION: The striker will re-cock if the slide is moved to the rear by about
.4” (10 mm). The trigger will remain in its forward-most position
(see Anti-Stress Trigger below).

• While holding the grip firmly, squeeze the trigger fully to the rear to fire.

• Keep your finger off the trigger and outside the trigger guard until you are ready to

fire again.

The subsequent shots will be fired with traditional Single Action trigger until the
P99 AS pistol is reset to Double Action by pressing the decocker.

19

3.4.4.2 P99 AS, Single Action Trigger

Traditional Single Action Trigger
After firing the first round all subsequent rounds will be fired with a traditional Single

Action trigger, until the pistol is reset to Double Action by pressing the decocker.
Anti-Stress Trigger

It is called “Anti-Stress” because the trigger pull of the P99 AS is the same length for
the first shot, regardless of whether it is double-action or single-action. The Anti­Stress trigger functions as a sort of two-stage trigger, and lessens the possibility of a
stress-induced unintentional discharge.

a) Shifting to Anti-Stress trigger mode by manually reloading
The Anti-Stress mode is activated each time the pistol is reloaded manually while the
finger is off the trigger.

b) Shifting to Anti-Stress trigger mode by manually cocking
The Anti-Stress mode is also activated each time the pistol is cocked manually while
the finger is off the trigger:
Hold the de-cocked pistol with your finger off the trigger and outside the trigger
guard, point the muzzle in a safe direction. Pull back the slide by about .4” (10 mm)
and then move it back to its forward position. This puts the pistol in Anti-Stress mode
(trigger in the forward-most position and the striker cocked).

If the slide gets pulled to the rear more than .8” (20 mm), a cartridge in the
chamber is ejected.

To fire a shot after such manual cocking, squeeze the trigger. When the trigger is
released, subsequent rounds will be fired using the traditional Single Action trigger
with a shorter trigger pull, until the P99 AS pistol gets reset to Double Action by
pressing the decocker.

3.5 Exchanging empty Magazines

Once the last round has been fired, the magazine follower exerts upward pressure on
the slide stop causing it to engage the slide stop notch thereby holding it in the
“open” position.

• Depress the magazine release and remove the magazine.

• To continue shooting, insert another loaded magazine.

• Pull the slide fully to the rear, let it go and allow it to run fully forward.

WARNING: THE PISTOL IS READY TO FIRE.
WITH THE MUZZLE STILL POINTING IN A SAFE DIRECTION, KEEP YOUR
FINGER OFF THE TRIGGER AND OUTSIDE THE TRIGGER GUARD UNTIL
READY TO FIRE .

20

3.6 Unloading the Pistol

WARNING: THE P99 PISTOL IS NOT EQUIPPED WITH A MAGAZINE
DISCONNECT FEATURE. THE P99 PISTOL WILL FIRE WITH THE
MAGAZINE REMOVED FROM THE PISTOL.

• Point the muzzle in a safe direction. Make sure your
finger is off the trigger and out of the trigger guard.
Depress the magazine release and remove the
magazine (3.6 Fig. 1).

• Keep the muzzle still pointed in a safe direction, and
keep your finger off the trigger and outside the
trigger guard.
Grasp the serrated sides of the slide from the rear
with the thumb and fingers (3.6 Fig. 2), and briskly
draw the slide fully rearward in order to extract any
cartridge from the chamber and clear it from the
pistol.
Do not obstruct the ejection port because doing so
can interfere with proper ejection of a cartridge.

• Lock the slide in the open position by allowing the
slide to move slightly forward from the rearmost
position while pressing upward on the slide stop
(3.6 Fig. 3).

• Visually check the barrel chamber to be sure it is
empty (3.6 Fig. 4).
Look into the chamber and down through the
magazine well. Verify that no ammunition remains in
the pistol.

3.6 Fig. 1

3.6 Fig. 2

3.6 Fig. 3

• Unload the magazine by holding it with the bullet
end of the cartridge pointing away from you and
pressing each cartridge forward and out of the
magazine.

Any time you release the slide while a magazine
containing cartridges is in the pistol, you will
have chambered a new round in the pistol. The

pistol will be ready to fire.

3.7 Clearing Misfires

WARNING: IF YOUR FIREARM GIVES ANY INDICATION THAT IT IS NOT
PERFORMING PROPERLY OR THE OPERATION OF YOUR FIREARM HAS
CHANGED “THE WAY IT FEELS OR SOUNDS”, STOP FIRING. MAKE
SURE THE FIREARM IS POINTED IN A SAFE DIRECTION, UNLOAD THE
FIREARM AND HAVE IT INSPECTED AND TEST- FIRED BY A GUNSMITH
QUALIFIED TO PERFORM SERVICE ON WALTHER FIREARMS.

• If a cartridge fails to fire, wait sixty seconds while keeping the muzzle pointed
in a safe direction.

• Keep your finger off the trigger and out of the trigger guard.

• Remove the magazine.

• Grasp the serrated sides of the slide from the rear and briskly pull the slide

fully rearward to eject the misfired round. Do not obstruct the ejection port, and
do not attempt to catch the round by placing your hand over the ejection port.
Also remember that any time you release the slide while a magazine
containing cartridges is in the pistol, you will have reloaded the chamber.

• In order to lock the slide in the open position, allow the slide to move slightly
forward from the rearmost position while pressing upward on the slide stop.

• Check the barrel chamber and bore visually for any obstructions. You must be
certain there are no cartridges in the chamber or obstructions in the barrel.
If there are any obstructions in the bore of the barrel have the pistol further
examined and repaired by a qualified gunsmith before using again.

4.3 Cleaning the Pistol

Your firearm is a precision instrument. To ensure the reliable function of the pistol, it
is necessary to establish routine maintenance procedures.

WARNING: CHECK THAT THE PISTOL IS UNLOADED (MAGAZINE
REMOVED FROM PISTOL AND CHAMBER CLEAR).
ALSO ENSURE THAT THE MAGAZINE IS UNLOADED.

After each use of the pistol or after being subjected to extreme weather conditions,
the pistol should be cleaned and lubricated. Also, before using the pistol for the first
time, it should be examined and cleaned. The pistol has been treated with either a
preservative or oil to protect it against corrosion. Before using it, all excess oil should
be wiped from the bore, chamber, and exposed areas using a clean swab or patch.

Field-strip the pistol as previously described. Starting with the barrel and from
chamber end, insert a brush through the bore of the barrel until the bristles
completely exit at muzzle end. Pull the brush back until the bristles completely exit at
chamber end. Use a good powder-removing solvent and brass bristle bore brush to
remove lead and firing residue from the interior of the barrel. Wipe the areas clean
with patches or a swab.

Using a small brush dipped in solvent, remove all deposits from around the breech
face, chamber end of the barrel, extractor and adjacent areas which have been
exposed to powder or primer residue. Remove any residue on the frame with light
brushing and a solvent. After cleaning, apply a light film of high quality gun lubricant
to all external metal surfaces and wipe clean.

WARNING: NEVER MANIPULATE, ADJUST OR CHANGE ANY OF THE
INTERNAL COMPONENTS OF YOUR FIREARM UNLESS SPECIFICALLY
DIRECTED TO DO SO IN THIS MANUAL. IMPROPER MANIPULATION OF
ANY INTERNAL COMPONENT MAY AFFECT THE SAFETY AND
RELIABILITY OF YOUR FIREARM AND MAY CAUSE SERIOUS INJURY OR
DEATH.

WARNING: ANY MAINTENANCE OR SERVICE NOT SPECIFIED IN THIS
MANUAL MUST BE PERFORMED BY A QUALIFIED GUNSMITH USING
GENUINE WALTHER PARTS. IF YOU DO OTHERWISE, IMPROPER
FUNCTIONING OF YOUR FIREARM MAY OCCUR AND SERIOUS INJURY
OR DEATH MAY RESULT.

If the pistol will be used or stored in a cold climate, be sure to use appropriate
lubricant that will not congeal at low temperatures.

CAUTION: Always follow the instructions provided with the gun cleaner and
gun lubricant. Some cleaners can cause damage to the pistol. You should
avoid prolonged solvent immersion and prolonged ultrasonic cleaning of the
pistol (maximum temperature for ultrasonic cleaning: 122 °F (50 °C)).
Choice of solvent should be restricted to those products specifically developed
for firearms maintenance. Damage to a firearm’s finish may occur if these
warnings are ignored.
Ammonia based solvents or other strong alkaline solvents, should not be used
on any WALTHER firearm.

27

4.4 Lubrication

After cleaning the entire pistol, use a cloth to apply a light film of high quality gun
lubricant to all external metal surfaces and wipe clean.
Do not over-lubricate the pistol to the extent where lubricant will be dripping or
running down the handgun. Excess lubricant can attract dirt, unburned powder and
carbon residue, which can interfere with proper functioning of the pistol.

• Barrel:
Use a cloth to apply a light film of high quality gun lubricant to all external surfaces
and the ramp where the locking block cams the barrel.

• Frame:
A light coat of high quality gun lubricant should be applied to the mechanism.
Put only one drop of lubricant on the slide guides, and on the trigger bar.
P99 DAO: Put a drop of lubricant on the lever next to the sear housing assembly.

• Slide:
Put only one drop of lubricant on the striker and on the safety plunger.
P 99 DAO: Put a drop of lubricant on the drop safety.

• Magazine:
Apply a light film of high quality gun lubricant to all external metal surfaces.

4.5 Maintenance before Storing

Obey all laws and regulations relating to the storage of firearms. You must familiarize
yourself with all local, state, and federal laws regarding the safe storage of firearms
and ammunition.
When storing the pistol, do not encase the firearm in anything that will attract or hold
moisture, such as leather or heavy cloth.
If the firearm is to be stored for an extended period, the bore, chamber and internal
working mechanism should be lubricated with a high quality lubricant or preservative
intended for firearms.
The external working mechanisms, slide, barrel, and magazine should be coated with
anti-corrosion lubrication.
Before using the pistol again, be sure to clean it. Every time you clean the firearm,
check it for signs of wear. If wear is noted, do not use the firearm. Return it to
WALTHER for service or have it checked by a qualified gunsmith.

5 Adjusting the Pistol to its User

WARNING: MAKE SURE THE HANDGUN IS UNLOADED BEFORE
ADJUSTING.

5.1 Grip

If the grip of the pistol does not fit your hand
comfortably, the backstrap can be replaced with
another size to better suit your hand.

To do so, push the pin in the bottom part of the
backstrap out using a punch (Full Size: 4mm /
Compact: 3 mm), exchange the backstrap for one
with a better fit and replace the pin (5.1 Fig. 1).
The P99 Full Size pistol backstraps are offered in
sizes Small, Medium, and Large. The P99 Compact
comes with backstraps in sizes Small and Large.

5.1 Fig. 1

5.2 Lanyard Loop

A lanyard loop for attachment of a lanyard is found at the lower end of the
backstrap (P99 Full Size only). The pin used to fasten the backstrap forms, together
with a recess in the backstrap, an eyelet for attachment of a lanyard.

To attach a lanyard, push the pin in the bottom part of the backstrap out using a
.15” (4 mm) punch, insert the lanyard, then replace the pin.

5.3 Sights

The front and rear sight are replaceable. The point of impact is adjustable for
windage and elevation. You can choose from polymer sights and steel sights and
different contrast markings.

WINDAGE
Polymer Rear Sight:

If shots group to the right, turn the rear sight windage screw
clockwise, if they group to the left, turn the windage screw counter
clockwise.
Adjustment by one click moves the impact point approximately
.7” (2 cm) at a distance of 25 yards (25 m) (5.3 Fig. 1).

5.3 Fig. 1

Replacing the polymer rear sight:

WARNING: While you remove the rear sight, be sure to control the rear sight
plunger so that it does not fly out.

Field-strip the pistol as described in section 4.1. Push down the rear sight plunger
and remove the rear sight to the left. If the rear sight is moved to the right, the
plunger can become lodged inside the rear sight. To rectify this, remove the rear
sight windage screw. Note that the rear sight windage screw is reverse threaded.

Install in reverse order.
CAUTION: Slide on polymer rear sight from left to right when installing it.

29

Steel Rear Sight:
Windage adjustments are made by drifting the steel rear sight from side to side with

the rear sight adjustment tool. If shots group to the right, move the rear sight to the
left, if they group to the left, move the rear sight to the right.

The standard WALTHER Steel Rear Sight (5.3 Fig. 2) will
fit very tightly into the slot cut in the slide. The rear sight
adjustment tool is available as an accessory and highly

recommended when adjusting for windage.
Do not remove the sleeve below the steel rear sight.

5.3 Fig. 2

ELEVATION
Elevation adjustments are made by using front sights of varying height.
Steel Front Sights of varying height are an accessory item.

If the shots group low, use a lower front sight. For high grouping, use a higher one.
The front sights are numbered. The higher the number, the higher the front sight.
Each stage results in a correction of the impact by about 2” (5 cm) over a 25 yards
(25 m) distance from target.

To change the front sight, field-strip the pistol as described in section 4.1.
Polymer Front Sight

Unscrew the front sight screw with the 1.3 mm Allen wrench from
the bottom of the front sight. Push the front sight out of the slide.

Assembly is in reverse order. Screw in the front sight screw until it
is flush with the base of the front sight (5.3 Fig. 3).

Steel Front Sight
Remove the front sight screw using a screwdriver and press the

front sight upwards and out.
Assembly is in reverse order (5.3 Fig. 4). Remember to make sure

the screw and the thread inside the steel front sight are free of oil
or grease. The thread of the front sight screw should be secured
using an industrial adhesive (for example Loctite 648). To tighten
the front sight screw, apply a torque of 8.8 inch lbs (1 Nm).

Note:
This handgun is not equipped with a

device that fully blocks use by
unauthorized users. More than
200,000 firearms like this one are
stolen from their owners every year
in the United States. In addition,
there are more than a thousand
suicides each year by younger
children and teenagers who get
access to firearms. Hundreds more
die from accidental discharge. It is
likely that many more children
sustain serious wounds or inflict
such wounds accidentally on others.
In order to limit the chance of such
misuse, it is imperative that you
keep this weapon locked in a
secure place and take other steps
necessary to limit the possibility of
theft or accident. Failure to take
