SAFETY IS YOUR

NUMBER ONE

RESPONSIBILITY!!!!

W

ARNING: YOU MUST FOLLOW
ALL OF THESE SAFETY RULES TO
ENSURE THE SAFE USE OF YOUR
FIREARM

• Safe gun handling is YOUR personal

responsibility at all times. Firear ms are dangerous

and can cause serious injury and death if they are
misused or used inappropriately. Safety must be the
prime consideration of anyone who owns or handles
firearms.

•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.

• Saf

e storage is your responsibility.

In particular,
you must secure firearms safely from children and
unauthorized users. A lock has been provided for
your use with this firearm. A lock is not a substitute
for safe and secure storage as defined in the “Safe
Storage and Transportation” section of this manual.

• Accidents are the result of violating the rules of
safe gun handling and common sense.

• For your safety and the safety of others, never
rel

y on mechanical features alone.

Only your
safe gun-handling habits will ensure the safe use of
your firearm. This is your responsibility.

•Ne

ver keep ammunition in the same location as

the handgun. Store in a separate and secure

place.

• READ

and UNDERSTAND these instructions

before using y

our firearm.

BASIC FIREARM

SAFETY RULES

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.

• BEFORE HANDLING ANY FIREARM,
UNDERSTAND ITS OPERA

TION.

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 Smith & Wesson
at 1-800-331-0852 before proceeding with its operation.

•AL

WAYS SAFELY STORE AND SECURE YOUR

•Y

OUR FIREARM IS YOUR RESPONSIBILITY.

Protect your firearm from theft or misuse by untrained or
unqualified individuals.

MAINTENANCE BEFORE ST

ORAGE

When storing, do not encase your firearm in anything that will attract or
hold moisture, for example, leather or heavy cloth. Also, do not store
guns with a plug inserted in the barrel for this can be a contributing
factor to moisture accumulation. If your firear m is to be stored for an
extended period, the bore, chambers and internal working mechanism
should be oiled with acid-free lubricating oil or preservative, and the
external working mechanisms, frame, cylinder and barrel should be
coated with an anti-rust oil. Before using your firearm again, be sure to
clean it. Every time you clean your firearm, check it for signs of wear.
If wear is noted, do not use the firearm. Return it to Smith & Wesson
for service or have it checked by a qualified gunsmith.

MAINTENANCE BEFORE USE

Before using your firearm, it should be cleaned. (See Cleaning
Instructions at page 24.) Your firearm 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, chambers (charge holes),
and exposed areas using a clean swab or patch. A light coat of high
quality gun oil should be applied to the outside surfaces and mecha­nism. Care should be taken not to oil the mechanism to the degree
that dust and lint may be trapped by the oil.

SAFE STORAGE & TRANSPORTATION CONT’D.

Smith & Wesson handguns are reliable and safe to use when
the basic firearm safety rules are followed. There are a
number of internal safety mechanisms within the
lockwork of the handgun which ensure that the firearm will
not discharge unless the trigger of the handgun is pulled.
That is one reason why it is important to never modify or
alter your firearm. Before you use your handgun, you
should be fully familiar with its operation.

Here is a list of basic firearms terminology.

AMMUNITION - CENTERFIRE

- Ammunition which
contains the primer in the center of the base of the case. Among
the most common centerfire handgun cartridges are the .32,
.38 Special, .380, 9mm, .357 Magnum®, .40 S&W®, .45 ACP
and the .44 Magnum®.

AMMUNITION - RIMFIRE

- Ammunition which contains the
primer material in the rim. Among the most common r imfire
handgun cartridges are the .22 Long, .22 Shor t, .22 LR, .22CB,
.22BB, and .22 Magnum.

CALIBER

- The diameter of a bullet, designated in
hundredths or thousandths of an inch (.357) or in
millimeters (9mm).

DECOCK

- The process by which the hammer or striker is

safely lowered.

NOMENCLATURE

9

NOMENCLATURE CONT’D.

DOUBLE ACTION -A firing action where the hammer or striker

is drawn back, released, and the gun fired by a single pull of the
trigger.

DOUBLE ACTION ONLY

-A firearm designed so that it can only

be fired in double action.

PIST

OL -A handgun that contains the cartridges in a magazine.

REVOLVER -A handgun that contains the car tridges in a

cylinder that revolves at the rear of the barrel.

SINGLE A

CTION -A firing action where the hammer or striker is

released from the cocked position by pulling the trigger.
The operation of your handgun will be explained in greater detail

in the pages that follow, as well as a greater description of key
component parts.

PREPARATION FOR

FIRING

AL

WAYS WEAR EYE AND EAR PROTECTION WHICH IS

SPECIFIED FOR FIREARM USE.

• Failure to wear adequate and proper ear protection on

even one occasion can potentially permanently damage
your hearing. Make sure others who are nearby are
wearing ear protection as well.

• Always wear safety glasses, whether indoors or out.

Safety glasses protect your eyes from the firing flash and
particles associated with the discharge of ammunition.

• DO NO

T SHOOT A

T HARD SURFACES, WATER OR UP

INTO THE SKY. Always select a place to shoot that has a

safe backstop, is free from obstructions and water surfaces
which cause ricochets.

• Alw

ays be aware of other people so that persons cannot

accidentally walk into the line of fire.

• Position the shooter and all others so that they are not

within an area where they may be struck by particle-spitting
from a revolver or by ejected cases from other types of
firearms.

• Keep fingers and other parts of your body away from the

muzzle and away from the gap between the revolver barrel
and cylinder, and away from the pistol slide and ejection
port.

• Be aler t and always follow the safety instruction of the

range officer.

PREPARATION FOR FIRING CONT’D.

10

• Be sure that all cylinders and actions of firearms are

open, that chambers are clear of cartridges,
magazines are removed, and that firearms are
pointing in a safe direction before anyone is allowed
in front of the firing position.

• Be aler t at all times. Never shoot if you are tired,

cold or impaired in any way.

• Treat your firearm as if it were loaded at all times.

AMMUNITION

PREPARATION FOR FIRING CONT’D.

A. GENERAL PRINCIPLES

• 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 impor tant to select the
proper ammunition for your firearm.

!! W

ARNING !!

• Never use ammunition not specifically designated for

use in your firearm. Failure to use the correct type or
caliber of ammunition may cause the firearm to jam, fail
to fire or even generate excessive pressure which can
damage or even rupture your firearm, causing personal
injury or property damage.

• You are responsible for selecting ammunition that meets

industry standards and is appropriate in type and caliber for
this firearm.

• Locate the caliber designation printed on the handgun.

This information indicates the ammunition caliber that
should be used in this firearm. (See figure #1)

B.

HANDLOADED OR RELOADED AMMUNITION

!! 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 to
the shooter or those in the
immediate vicinity.

FIGURE 1

11

• 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).

• Be certain all ammunition you use complies with the

SAAMI specifications. If you are uncer tain, contact your
ammunition supplier for verification.

C.

MISFIRES

• If your firearm fails to fire when the trigger is pulled

(misfires), keep the firearm pointed in a safe direction,
remove your finger from the trigger, and wait 10 seconds.
Only after you have completed all of the above steps,
remove the magazine or open the cylinder and remove the
cartridge from the chamber and dispose of it properly.
Keep your firearm pointed in a safe direction at all times.

• If you have heard an unusual sound or felt an unusual recoil

on firing, stop firing, wait 10 seconds, unload the firearm,
and examine the barrel bore for obstructions.

• Make sure your barrel is clear and free of obstructions.

If you see an obstruction, return your firearm to
Smith & Wesson or take it to a qualified gunsmith. Never
fire a firearm with an obstructed barrel.

D

. AMMUNITION SPECIFICS

• Use only ammunition specifically recommended by

Smith & Wesson for your firearm.

• Never mix ammunition.

• Never use a cartridge not specifically designated for use in

your firearm. Pressure from the wrong type of ammunition
may be beyond the capability of your firearm to withstand
and may damage or even rupture your firearm.

• Whenever rimless pistol cartridges are used in the cylinder

of a Smith & Wesson revolver, (except M547) full or
half-moon clips MUST be used to both position and extract
such cartridges. Failure to use ammunition clips with
rimless cartridges may result in malfunction of the revolver.

• Additional ammunition calibers can be fired from the

following list of select calibers.

Caliber on Barrel

Can also Fire
.45 Colt .45 Schofield, .45 S&W
.45 S&W .45 Schofield
.44 Magnum .44 Special
.357 Magnum .38 Special, .38 Special +P
.22LR .22L, .22 Short, .22CB, .22BB
10mm .40 S&W (in revolvers only)

• In some cases, a round of ammunition not specified on your

handgun may fit into the chamber or cylinder. Firing
ammunition not specified on your handgun may cause it to
rupture and cause serious injury or death.

AMMUNITION CONT’D.

12

AMMUNITION CONT’D.

E. AMMUNITION WARNINGS

• “Plus-P” (+P) ammunition generates pressures in excess of

the pressures associated with standard ammunition. Such
pressures may affect the wear characteristics or exceed the
margin of safety built into some revolvers and could
therefore be DANGEROUS.

• “Plus-P” ammunition should not be used in medium

(K frame) revolvers manufactured prior to 1958. Such
pre-1958 medium (K-frame) revolvers can be identified by
the absence of a model number stamped inside the yoke
cut of the frame. (i.e., the area of the frame exposed when
the cylinder is in the open position.

• “Plus-P-Plus (+P+) marking on the ammunition merely

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.

• “Plus-P-Plus (+P+) ammunition is not recommended for use

in Smith & Wesson firearms.

• In the Model 940 revolver, some brands of 9mm parabellum

ammunition may cause difficulty in extracting spent
cartridge cases from the cylinder. If this situation occurs,
thoroughly clean the cylinder charge holes with solvent. If
this condition persists, we recommend changing to another
brand of 9mm parabellum ammunition.

• Smith & Wesson has found wide variations in primer

sensitivity between some brands and types of .22LR
ammunition. Smith & Wesson recommends that before you
put your .22LR handgun into regular use, that you fire
several boxes of your choice of ammunition through it to
determine reliability of ignition. If “failure to fire” occurs, tr y
different types of brands of .22LR ammunition until a
reliable loading is found.

INSPECTING YOUR

PISTOL

When you inspect your pistol, you should first check for yourself
to ensure that it is unloaded.To do this, grasp the pistol with
your finger off the trigger and outside the tr

igger guard, point the
pistol in a safe direction, depress the magazine release, and
remove the magazine.

With the pistol still pointing in a safe direction, grasp the
serrated sides of the slide from the rear with the thumb and
fingers as shown in Figure 3, and briskly draw the slide fully
rearward in order to extract any cartridge from the barrel
chamber and clear it from the pistol. Do not obstr uct the ejection
port because doing so can interfere with ejection of a cartridge
and thereby creates the risk of exploding an unchambered
cartridge and possible injury.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. You are now
able to safety check the barrel chamber and magazine well
(opening) visually for any obstructions (Figure 3a).You must
follow this procedure every time your firearm is inspected,
cleaned, handed to another person, transported or stored.
Unload the magazine by holding it with the bullet end of the
cartridge pointing away from you and others and pressing each
cartridge forward and out of the magazine.

FIGURE 3

LOADED CHAMBER

INDICATOR

Currently manufactured Sigma Pistols come with a loaded
chamber indicator. This indicator can be observed by looking at
the top of the slide/ejection port, (Figure 4) noting an opening at
the rear of the barrel hood. By looking into this opening, you
can observe as to whether or not a round is in the firearm’s
chamber. You would see the actual brass or silver colored rim
through this opening if the chamber of the firearm was loaded.

FIGURE 4

FIGURE 3a

LOADING

• Do not load the pistol until you are ready to use it.

Keep your finger outside the trigger guard until you are ready
to fire.

WARNING: SMITH & WESSON SIGMA SERIES
PISTOLS ARE CAPABLE OF FIRING EVEN WHEN THE
MAGAZINE HAS BEEN REMOVED IF THE TRIGGER IS
PULLED.

If the magazine is removed with a round left in the chamber, be
sure to holster or otherwise safely secure the pistol under your
direct control while the magazine is being reloaded.

• Only use Smith & Wesson magazines specifically
manufactured for your particular model of pistol. Do not
interchange magazines from one model pistol into another
model pistol.

• Smith & Wesson 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.

•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 Smith &
Wesson magazine specified for your model and caliber of
pistol may result in a malfunction.

• Load the magazine by pressing a cartridge head (rear of
cartridge) downward on the forward portion of the magazine
follower (or downward on the case of the previously loaded
cartridge) and sliding the car tridge fully under the lips of the
magazine until the cartridge head 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.
Do not attempt to load your magazine with more than the
specified number of cartridges because doing so can cause
a feeding failure.

• Inspect your pistol as previously described in the “Inspecting
Your Pistol” section. Hold the pistol in one hand while
pointing it in a safe direction and with your finger off
the trigger and outside the trigger guard. Inser t the loaded
magazine into the magazine well (opening) with enough
force to ensure that it is locked in place.

15

FIGURE 5

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.

•To make sure that the magazine is fully and securely
inserted, apply some removal pressure to the exposed
portion of the magazine butt plate.

• Press down on the slide stop to release the slide and allow it
to carry fully forward. This strips a car tr idge from the
magazine and seats it in the chamber of the barrel.

•Take this opportunity to look into the loaded chamber
indicator. If the loading procedure has been properly
followed, you will observe the rim of the cartridge that
you have just loaded into the chamber from the magazine.

The pistol can now be fired by pulling the trigger to the rear.

• 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 and the trigger should
never be moved. Load one car tr idge 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 is 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 unattended.

LOADING CONT’D.

CAUTION

FIRING

•Keep the pistol pointed in a safe direction and your finger
outside the trigger guard until you are ready to fire. Each
shot will be fired in the double action mode.While holding
the grip firmly, pull the trigger fully to the rear. As the trigger
is drawn fully to the rear, the striker assembly is released,
striking the cartridge pr imer. Upon fir ing 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 barrel chamber.

WARNING: When viewing the loaded chamber
indicator, you must always remember to keep the
firearm pointed in a safe direction with your finger
off the trigger and out of the trigger guard.
(Figure 7)

• After firing you must allow the trigger to move forward fully
before you can fire another shot.Failure to do so will prevent
the lockwork from fully cycling and will prevent your 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, at which time the magazine follower exerts upward
pressure on the slide stop causing it to engage the slide and
to hold it in the “open” position.

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
interferes with the slide movement or ejection of
fired case.

FIGURE 7

18

CLEARING MISFIRES

•If, dur ing firing, a cartridge fails to fire, the chamber must be
manually cleared.Wait ten seconds while keeping the pistol
pointed in a safe direction. Grasp the serrated sides of the slide
from the rear and briskly pull the slide fully rearward to eject the
misfired round. Keep your finger off of the trigger and out of the
trigger guard. Do not obstruct the ejection por t, and do not
attempt to catch the round by placing your hand over the ejection
port. (See figure 8) Also, remember that any time you release the
slide while a magazine containing cartridges is in the pistol, you will
have reloaded the chamber

PRODUCT WARNING

All Smith & Wesson Handguns Capable of Double Action
Firing

• It has come to our attention that some users of
Smith & Wesson pistols capable of firing in double action
may stage the trigger in anticipation of firing a shot in the
double action mode.Staging is the act of pulling the trigger
rearward toward — but just short of — the point where the
hammer falls and the pistol fires.Such manipulation of the
trigger can reduce the user’s control of the handgun and can
result in an unintentional discharge. Fur ther more 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
a discharge.

•Obviously “staging” the trigger violates a basic rule of firearm
safety which warns you to keep your finger off the trigger and
outside the trigger guard until ready to fire.

•We warn all users of our pistols capable of firing in double
action to refrain from “staging” the trigger.

UNLOADING

•Point the pistol in a safe direction, grasp the serrated sides of
the slide from the rear with the thumb and fingers as shown in
Figure 9, and briskly draw the slide fully rearward in order to
extract any cartridge from the barrel chamber and clear it
from the pistol. Do not obstr uct the ejection por t because
doing so can interfere with ejection of a cartridge and thereby
creates the risk of exploding an unchambered cartridge and
possible injury. 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. You are now able to
safety check the barrel chamber and bore visually for any
obstructions.You must follow this procedure every time your
firearm is inspected, cleaned, handed to another person,
transported or stored. Unload the magazine by holding it with
the bullet end of the cartridge pointing away from you and
others and pressing each cartridge forward and out of the
magazine.

WARNING:
You should never rely completely on the loaded
chamber indicator only, but should always
perform a visual check. With the pistol’s slide
locked open, visually check the pistol’s chamber
and magazine well (opening) to ensure that they
are empty.

FIELD STRIPPING

DISASSEMBLY

WARNING: SAFETY GLASSES SHOULD BE WORN
DURING THIS PROCESS.

•Point the pistol in a safe direction. Make sure your finger is
off the trigger, and the trigger is in the "at rest" or forward
position. Depress the magazine release, and remove the
magazine. (Figure 10) With the barrel still pointing in a safe
direction, and with 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 while holding the firearm in
an upright position, and briskly draw the slide fully rearward
in order to extract any cartridge from the barrel chamber and
clear it from the pistol.

WARNING: The recoil spring is under pressure .
Control the recoil spring and the guide so that they
do not fly out and cause injury.

• Remove the recoil spring and barrel. (Figure 16)

NOTE:

No further disassembly is recommended, as the pistol may be
properly cleaned and lubricated when field-stripped as described
above.

• Make certain that the
chamber is clear.(Figure 11)

• With the pistol still pointing in
a safe direction and the slide
closed, pull the trigger once
and remove your finger from
the trigger and out of the
trigger guard. (Figure 12)

•Move the slide approximately 1/8” (Figure 13) to the rear and
depress the takedown catch/barrel stop on both sides of the
frame with your thumb and forefinger. (Figure 14)

• Allow the slide to return forward while depressing the
takedown catch/barrel stop.(Figure 14-15)

•Grasp the slide from the top, just behind the front sight and
remove the slide by pulling it forward while being careful to
retain the recoil spring and guide rod assembly. (Figure 15)

WARNING:
To complete disassembly, you will be required to

pull the trigger. If you have failed to properly
unload your pistol and a round is left in the chamber, the
pistol will discharge and may cause injury. Therefore, you
must visually inspect the chamber and magazine well
(opening) to ensure that they are empty before pulling the
trigger.

FIELD STRIPPING

REASSEMBLY

• With the rear of the slide pointed in a safe direction and the
bottom of the slide turned up, replace the barrel in the slide
so the muzzle is flush with the end of the slide and the barrel
lug is turned up (away from the ejection port). Replace the
recoil spring on the recoil spring guide. Insert the spring end
of the recoil spring guide assembly in the guide housing.
(Figures 18 & 19)
Grasp the recoil spring guide bushing and pull it toward you
enough so the bushing can be securely engaged in the small
radial machine cut in the barrel lug. Be careful that it does
not become disengaged, fly out and cause injury.Make sure
it is properly centered in the cut as it will protrude from the
slide after assembly if it is not centered.
(See Figures 20a & 21a)

LUBRICATION

There are six (6) lubrication points where a single drop of
firearms lubricant should be applied. This will assure proper
lubrication of your sigma series pistol. Care should be taken not
to over-lubricate. Excess lubr icant can collect large quantities of
unburnt powder and carbon residue, which could interfere with
proper functioning of the pistol.

FIGURE 25

FIGURE 24

CLEANING AND

MAINTENANCE

!! WARNING !!

Ensure your pistol is unloaded before beginning to clean it.
At all times follow the basic rules of safe gun handling.

Your pistol is a precision instrument and to insure reliable
function, it is necessary to follow a routine maintenance
procedure. After firing your pistol, be sure to unload it following
the procedure outlined in the section entitled “Unloading” on
page 19 before any cleaning or maintenance procedure. Your
pistol should be cleaned by brushing the barrel bore and
chamber with a good powder-removing solvent and bore brush.
Wipe the areas clean with patches or a swab. Using a small
brush dipped in solvent, remove all deposits from around the
breech of the barrel, and chamber, extractor and adjacent areas
which have been subjected to the action of powder or primer
residue. Remove any residue on the frame with light brushing
and a solvent. After cleaning the entire gun, use a cloth to apply
a light film of high quality gun oil to all external surfaces and
wipe clean.

CAUTION: You should avoid prolonged solvent emersion and
prolonged ultrasonic cleaning of your firearm. Choice of solvent
should be restricted to those products specifically developed for
firearms maintenance. Instances of damage to a firearm’s finish
have been recorded when these cautions have been ignored.
Ammoniated solvents which are chemically basic should not be
used on any Smith & Wesson firearm. As a rule of thumb, if you
would be comfortable applying the solvent of your choice to the
finish of your automobile, it will probably be safe for use on your
firearm.

After the initial cleaning, there is usually some residue in both
the barrel and cylinder that works out and becomes apparent
within 24-48 hours. This can be removed with a bristle brush
and a light re-application of powder removing solvent after which
the oil film should be re-established on all surfaces.

Cleaning is considered essential in order to ensure the proper
functioning of your handgun.

For additional maintenance, we recommend the services of a
qualified gunsmith. Please refer to section entitled “Service”. If
your firearm will be used or stored in a cold climate, be sure to
use an oil that will not thicken at low temperatures.

NOTES

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 reason­able preventative steps may result in inno­cent lives being lost, and in some circum­stances may result in your liability for
these deaths.

The certification below is required only for handguns sold in the
United States with a barrel length shorter than 3”.

Smith & Wesson Corp. hereby certifies average accuracy test results for
all new handguns with a barrel shorter than 3” as follows:

7 yards 14 yards 21 yards

1.7” 3.9” 6.3”

This certification is based on tests conducted by Smith & Wesson Corp.
using a fixed handgun, rest and firing ammunition manufactured by a
member of the Shooting Arms and Ammunition Manufacturers Institute
(SAAMI) as defined in ANSI/SAAMI Z299.3-1993.

This certification represents actual tests based on several handguns,
selected at random. Your particular handgun may have accuracy better
than the results stated in this certification. Any caliber handgun not
specifically listed will perform comparably to the nearest caliber listed.
