General Instructions
Always assume that the KAHR Pistol or
any other firearm is loaded and capable
of being discharged until you, the handler, have personally verified the fact.
Until the magazine is removed and you
have inspected the chamber and completed the unloading procedure as presented on page 9, the firearm must be
considered loaded and capable of being
fired. Never transport a loaded firearm.
To reduce the possibility of an unintentional discharge, do not place your finger on the trigger until the firearm is
pointed at the target and you intend to
fire. When handling, carrying or holstering the pistol be sure that the trigger
cannot be snagged by a foreign object.
This can discharge the pistol.
If you don’t want the firearm to fire, keep
your finger off the trigger.
When firing with a two hand grip, keep
the thumb of the weak hand on the weak
hand side of the firearm, never behind
the slide.
Before using the KAHR Pistol, completely
read and fully understand the operating
instructions and safety information in
this manual. If you have difficulty understanding anything in this manual, call
Kahr Technical Support at (508) 791-3919
or seek qualified instruction in the safe
use of the KAHR Pistol and other handguns.
Important Safety Information
Caution:
Law enforcement, military personnel and
certain individuals may choose, for self
defense purposes, to disregard or override several of the following safety
instructions. To assure safety under
these special situations, proper initial
combat oriented training with periodically scheduled retraining, which stresses
safe tactical procedures, is strongly recommended.

Caution:
Failure to observe safety instructions in
this manual can result in property damage, personal injury or death.
Caution:
Prior to loading and firing, carefully read
and understand this instruction manual.
It gives basic advice on the proper handling and functioning of the KAHR Pistol.
Any firearm, including the KAHR Pistol, is
a dangerous device. All firearms must be
safely stored to prevent access by unauthorized persons, especially children.
Always store ammunition separately
from firearms.
This manual is applicable only to the
KAHR Pistol with which it was included.
All instructions, warnings and precautions are not applicable to any other
make or model.
For all sales contracts with KAHR, the
place of jurisdiction shall be Delaware,
and Delaware State Law shall be applicable.
General Description
The KAHR Pistol, with its all-steel design,
incorporates the key features most
desired in a personal defensive handgun:
• Low overall weight
• Extremely compact size
• Outstanding quality of
materials and workmanship
The KAHR Pistol is a mechanicallylocked, recoil operated pistol with a passive striker block and a trigger-cocking
(D/A Only) action.
Each round is automatically loaded until
the magazine is empty. The slide is then
held open by the slide release lever.
Primary Features
The KAHR Pistol trigger system allows
the shooter to quickly bring the pistol into
action by eliminating the need to operate
any manual safeties. Once the target has
been selected and identified, simply
pulling the trigger fires the pistol.
The striker is automatically held under
partial tension after each round and is
fully secured by a passive striker block
until the trigger is fully depressed.
The slide release lever and the magazine catch are easily operated with the
shooting hand.
The KAHR Pistol frame is uniquely
designed to position the shooting hand
as close to the center line of the bore as
possible. This provides the benefit of
greater control and a perceived reduction in recoil.
The all-steel construction and sophisticated computerized manufacturing technology employed in the construction of
the KAHR Pistol assure superior quality
and reliability.
Technical specifications may be altered
without notice.
Important Safety Information
Caution:
Your safety and the safety of your family
and others depends on your safe and
mature adoption, development and consistent employment of SAFE FIREARMS
HANDLING PRACTICES.If you are unfamiliar with firearms, seek further advice
through safe handling courses run by
your local gun clubs, approved instructor,
or similar qualified organizations.
Warning:
It is possible that a live round may remain
in the chamber when the magazine has
been removed or inserted. Any round in
the chamber will discharge upon pulling
the trigger regardless of whether the magazine is inserted or removed. Therefore,
never leave the pistol unattended, even if
the magazine is removed and exercise
extreme caution after removing the magazine.

How the Kahr Pistol Functions
FOR TESTING FUNCTION, ALWAYS USE
AN UNLOADED PISTOL WITH AN
EMPTY CHAMBER AND WITHOUT THE
MAGAZINE INSERTED.
(described immediately below)
1. Without placing finger on the Trigger,
remove the Magazine. Make sure that
there is no round in the chamber by
pulling the Slide fully to the rear and
carefully checking that the chamber is
empty. The pistol is now unloaded with
the Magazine out.
2. Keeping finger off the Trigger, cock the
pistol by pulling the Slide fully to its
rearmost position and letting it run forward. The pistol is now partially cocked,
i.e. the Striker Spring is partially tensioned. The Trigger is fully forward.
The following describes the functioning of
the KAHR Pistol when it is loaded and
fires:
As the Trigger is pulled (pressed to the
rear), the internal passive Striker Block is
released, i.e. a protrusion on the
Cocking Cam lifts the Striker Block so
that it no longer blocks the Striker from
moving forward past the breech face to
fire a chambered round. Simultaneously
with this action, the Cocking Cam pulls
the Striker back from half-cock to a fully
cocked position under full spring tension.
Completing the rearward pull of the
Trigger allows the Cocking Cam to
release the Striker. With the Striker Block
lifted, the Striker is free to move fully forward to contact and fire the cartridge.
The recoil impulse of the fired cartridge
moves the Barrel and Slide backwards.
After approximately
1/2 inch of movement to the rear,
the camming action of the recoil lug of
the Barrel and the pin on the Slide
Release Lever in the Frame pulls the rear
of the Barrel down to unlock it from the
Slide. Unlocked, the Slide continues
fully to the rear of its travel. During this
rearward travel, the cartridge is pulled
out of the chamber by the Extractor and
is then thrown out to the right by the
Ejector.
A ramp in the Slide rails disengages the
Trigger Bar from the Cocking Cam. This
allows the Cocking Cam to reset itself
and reactivates the Striker Block.
The Recoil Spring begins to move the
Slide forward toward its original locked
position.
As the Slide moves forward:
1. a loaded round is pushed out of the
magazine into the chamber;
2. the Striker is caught and put under
partial tension by the Cocking Cam, and 3.
the Barrel is pushed forward and
upward, locking it with the Slide.
Important Safety Information
Warning:
The KAHR Pistol has no external, manual safety lever and no grip safety. It is
fired like a double-action revolver by
pressing the trigger. Always keep the
firearm unloaded until you are ready to
shoot. When the firearm is loaded do
not touch the trigger unless you intend
to fire!
6
Warning:
If the KAHR Pistol appears to be operating improperly for any reason, danger
of an unintentional discharge exists.
The firearm must be immediately
unloaded and not used until it is
repaired. Make sure that the pistol is
properly repaired and checked by
KAHR ARMS or an authorized gunsmith
before using it again.
