access to the firearm. Store your firearm responsibly!”
MASSACHUSETTS:
“WARNING FROM THE MASSACHUSETTS ATTORNEY GENERAL: 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.”

WARNING - LOCKING DEVICES
This firearm was originally sold with a keyoperated locking device. While it can help
provide secure storage for your unloaded
firearm, any locking device can fail. All guns
are designed to fire if they are loaded and
the trigger is pulled. Therefore, never install
the locking device inside the trigger guard or
in any way that makes it possible to pull the
trigger! Do not leave the keys in the lock.
The ultimate responsibility for secure storage
of any firearm must depend upon its owner
and his or her individual circumstances.
Firearms should be stored unloaded, in
a secure location, separate from their
ammunition.
NEVER INSTALL THE
LOCKING DEVICE INSIDE
THE TRIGGER GUARD
To maximize effectiveness and reduce the chances of malfunction or damage
to a firearm, ALWAYS refer to the locking device’s manufacturer directions for
installation and removal of the device.

FIREARMS ARE DANGEROUS WEAPONS
READ THE INSTRUCTIONS AND WARNINGS IN
THIS MANUAL THOROUGHLY AND CAREFULLY
BEFORE USING.
WARNING - ALTERATIONS
This product was designed to function properly in its original
condition. Alterations can make it unsafe. Do not alter
any part or add or substitute any parts or accessories not
manufactured by SIG SAUER, Inc. for this pistol.
DO NOT ALTER ANY GUN

1.0 Safety Rules
The safety warnings in this manual are important. By understanding the dangers
inherent in the use of any firearm, and by taking the precautions described herein,
you can experience a higher level of safety in the use of your pistol. Failure to
heed any of these warnings may result in serious injury to you or others, as well
as severe damage to the firearm or other property.
PISTOLS are classified as FIREARMS and are sold by SIG SAUER with the specific
understanding that we shall not be responsible in any manner whatsoever for
malfunctioning of the firearm, physical injury or property damage resulting in
whole or in part from:
• criminal or negligent discharge;
• improper or careless handling;
• unauthorized modifications;
• defective, improper, hand-loaded, or reloaded ammunition;
• corrosion;
• neglect; or
• other influences beyond our direct and immediate control.
This limitation applies regardless of whether liability is asserted on the basis
of contract, negligence, or strict liability (including any failure to warn). Under
no circumstance shall SIG SAUER, Inc. be liable for incidental or consequential
damages, such as loss of use of property, commercial loss, and loss of earnings
or profits.
1.1 Protect Your Eyes and Ears
Always wear safety glasses that meet the requirements of American National
Standards Institute (ANSI) Z87.1 and ear plugs or “earmuff” type protectors
whenever you are shooting. Always make certain that persons close to you
are similarly protected. Unprotected eyes may be injured by powder, gas,
carbon residue, lubricant, metallic particles, or similar debris that may emanate
occasionally from any firearm in normal use. Without ear protection, repeated
exposure to shooting noise may lead to cumulative, permanent hearing loss.

2.0 Mechanical Characteristics and Weapon
Theory
2.1 Weapon Description
2.1.1. General
The SIG SAUER P320 pistol is a modern handgun incorporating the latest technical
advances in weapon design for military, law enforcement and sporting use. The P320
is a mechanically locked, short recoil operated pistol with semi-automatic reloading.
Firing takes place with each pull of the trigger until the magazine is empty. The slide
remains open after the last round has been fired from the magazine.
2.1.2 Principal Features
The automatic striker assembly lock and double-action trigger ensure safe
carrying of the weapon and provide instant readiness without actuating a manual
safety.
Distinctive high-contrast sights, in conjunction with the ergonomically correct
grip, ensure rapid target acquisition and engagement, even under poor lighting
conditions.
Interchangeable grip modules of different sizes allow for optimal adaptation of the
weapon to the individual user.
The magazine catch can easily be reconfigured for left or right-hand operation. All
other operating controls are designed so they can be operated from either side.
A Picatinny rail is integrated into the grip module, facilitating the easy attachment of
industry standard tactical accessories.
The closed design of the pistol helps keep dirt and other debris from entering the
pistol, ensuring proper function in harsh environmental conditions.
The P320 pistol is a double-action only (DAO) design.

3.0 Ammunition
1. Use only high-quality, original, factory-manufactured ammunition. Do not use
cartridges that are dirty, wet, corroded, bent, or damaged. Do not oil cartridges.
Do not spray aerosol-type lubricants, preservatives, or cleaners directly onto
cartridges or where excess spray may flow into contact with cartridges. Lubricant
or other foreign matter on cartridges can cause potentially dangerous ammunition
malfunctions. Only use ammunition of the caliber for which your firearm is
chambered. The proper caliber is permanently engraved on your firearm; never
attempt to use ammunition of any other caliber.
2. The use of reloaded, “remanufactured” hand-loaded, or other non-standard
ammunition voids all warranties. Reloading is a science and improperly loaded
ammunition can be extremely dangerous. Severe damage to the firearm and
serious injury to the shooter or to others may result. Always use ammunition that
complies with the industry performance standards established by the Sporting
Arms and Ammunition Manufacturers’ Institute, Inc. (SAAMI) of the United States
or ammunition manufactured to military specifications.
WARNING – AMMUNITION (CARTRIDGE)
NOTICE
SIG SAUER SPECIFICALLY DISCLAIMS RESPONSIBILITY FOR ANY DAMAGE OR
INJURY WHATSOEVER OCCURRING IN CONNECTION WITH, OR AS A RESULT
OF, THE USE IN ANY SIG SAUER FIREARM OF FAULTY, NON-STANDARD,
“REMANUFACTURED” HAND-LOADED (RELOADED) AMMUNITION, OR CARTRIDGES
OTHER THAN THOSE FOR WHICH THE FIREARM WAS ORIGINALLY CHAMBERED.
14
www.sigsauer.com
3. Firearms may be severely damaged and serious injury to the shooter or to
others may result from any condition causing excessive pressure inside the
chamber or barrel during firing. Excessive pressure can be caused by obstructions
in the barrel, propellant powder overloads, the use of incorrect cartridges, or
defectively assembled cartridges. In addition, the use of a dirty, corroded, or
damaged cartridge can lead to a burst cartridge case and consequent damage
to the firearm and personal injury from the sudden escape of high-pressure
propellant gas within the firearm’s mechanism.
4. Immediately stop shooting and check the barrel for a possible obstruction
whenever:
• You have difficulty in, or feel unusual resistance in, chambering a cartridge
• A cartridge misfires (does not go off)
• The mechanism fails to extract a fired cartridge case
• Unburned grains of propellant powder are discovered spilled in the
mechanism
• A shot sounds weak or abnormal. In such cases it is possible that a bullet
is lodged partway down the barrel. Firing a subsequent bullet into the
obstructed barrel can wreck the firearm and cause serious injury to the
shooter or to bystanders
5. Bullets can become lodged in the barrel:
• If the cartridge has been improperly loaded without propellant powder, or
if the powder fails to ignite (ignition of the cartridge primer alone will push
the bullet out of the cartridge case, but usually does not generate sufficient
energy to expel the bullet completely from the barrel).
• If the bullet is not properly seated in the cartridge case. When such a
cartridge is extracted from the chamber without being fired, the bullet may
be left behind in the bore at the point where the rifling begins. Subsequent
chambering of another cartridge may push the first bullet further into the
bore.
www.sigsauer.com
15
6. If there is any reason to suspect that a bullet is obstructing the barrel,
immediately unload the firearm and look through the bore. It is not sufficient to
merely look in the chamber.
A bullet may be lodged some distance down the barrel where it cannot easily be
seen.
WARNING – LODGED BULLET
IF A BULLET IS IN THE BORE, DO NOT ATTEMPT TO SHOOT IT OUT BY USING
ANOTHER CARTRIDGE OR BY BLOWING IT OUT WITH A BLANK OR ONE FROM WHICH
THE BULLET HAS BEEN REMOVED. SUCH TECHNIQUES CAN GENERATE EXCESSIVE
PRESSURE, DAMAGE THE FIREARM, AND CAUSE SERIOUS PERSONAL INJURY.
If the bullet can be removed with a cleaning rod, clean any unburned powder
grains from the bore, chamber, and mechanism before resuming shooting. If the
bullet cannot be dislodged by tapping it with a cleaning rod, send the firearm to
SIG SAUER.
7. Dirt, corrosion, or other foreign matter on a cartridge can impede complete
chambering and may cause the cartridge case to burst upon firing. The same is
true of cartridges that are damaged or deformed.
8. Do not oil cartridges, and be sure to wipe the chamber clean of any oil or
preservative before commencing to shoot. Oil interferes with the friction between
cartridge case and chamber wall that is necessary for safe functioning, and
subjects the firearm to stress similar to that imposed by excessive pressure.
9. Use lubricants sparingly on the moving parts of your firearm. Avoid
excessive spraying of any aerosol gun care product, especially where it may
get on ammunition. All lubricants and aerosol spray lubricants, in particular,
can penetrate cartridge primers and cause misfires. Some highly penetrative
lubricants can also migrate inside cartridge cases and cause deterioration of the
propellant powder; on firing, the powder may not ignite. If only the primer ignites,
there is danger that the bullet may become lodged in the barrel.

WARNING - AMMUNITION
Death, serious injury, and damage can result
from the use of wrong ammunition, bore
obstructions, powder overloads, or incorrect
cartridge components. Always wear shooting
glasses and hearing protectors.
IMPROPER AMMUNITION DESTROYS GUNS
WARNING - LEAD EXPOSURE
Discharging firearms in poorly ventilated areas,
cleaning firearms, or handling ammunition may
result in exposure to lead and other substances
known to the state of California to cause birth
defects, reproductive harm, and other serious
physical injury. Maintain
adequate ventilation at all times. Wash hands
thoroughly after exposure.
SHOOTING OR CLEANING GUNS MAY EXPOSE YOU TO LEAD

WARNING – LOADED PISTOL
The pistol is now loaded and ready to fire.
Always make sure the muzzle is pointed in a safe direction! Never attempt to
load or unload any firearm inside a vehicle,building, or other confined space
(except a properly constructed shooting range). Enclosed areas frequently offer no
completely safe direction to point the firearm; if an accidental discharge occurs,
there is great risk of bodily injury or property damage. Before loading, always
clean all grease and oil from the bore and chamber, and check to be certain that
no obstruction is in the barrel. Any foreign matter in the barrel could result in a
bulged or burst barrel or other damage to the firearm, and could cause serious
injury to the shooter or to others.
