“Children are attracted to and
can operate firearms that can
cause severe injuries or death.
Prevent child access by always
keeping guns locked away and
unloaded when not in use. If you
keep a loaded firearm where a
child obtains and improperly uses
it, you can be fined or sent to
prison.”

State-By-State Warnings
Certain states require by law that their own specified warning
notices in larger-than-normal type be conspicuously included by
the manufacturer, distributor, or retail dealer with firearms sold
in that state. Sturm, Ruger sells its products in compliance with
applicable laws and regulations. Because our products may be
sold in these states, we include the following:
California:
“A los niños los atraen las armas
de fuego y las pueden hacer
funcionar. Ellos pueden causarses
lesions graves y la muerte. Evite
que los niños tengan accesso a las
armas de fuego guardándolas
siempre con llave y descargadas
cuando no las esté utilizando. Si
usted tiene un arma de fuego
cargada en un lugar en que un
niño tiene acceso a ella y la usa
indebidamente, le pueden dar una
multa o enviarlo a la carcel.”
Connecticut:
“UNLAWFUL STORAGE OF A LOADED FIREARM MAY
RESULT IN IMPRISONMENT OR FINE.”
Florida:
“IT IS UNLAWFUL, AND PUNISHABLE BY
IMPRISONMENT AND FINE, FOR ANY ADULT TO
STORE OR LEAVE A FIREARM IN ANY PLACE WITHIN
THE REACH OR EASY ACCESS OF A MINOR UNDER 18
YEARS OF AGE OR TO KNOWINGLY SELL OR
OTHERWISE TRANSFER OWNERSHIP OR POSSESSION
OF A FIREARM TO A MINOR OR A PERSON OF
UNSOUND MIND.”
Maine:
“ENDANGERING THE WELFARE OF A CHILD IS A
CRIME. IF YOU LEAVE A FIREARM AND AMMUNITION
WITHIN EASY ACCESS OF A CHILD,YOU MAY BE
SUBJECT TO FINE, IMPRISONMENT OR BOTH. KEEP
FIREARMS AND AMMUNITION SEPARATE. KEEP
FIREARMS AND AMMUNITION LOCKED UP. USE
TRIGGER LOCKS.”
Maryland:
“WARNING: Children can operate firearms which may cause
death or serious injury. It is a cr
ime to store or leave a loaded
firearm in any location where an individual knew or should
have known that an unsupervised minor would gain 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 preventive steps may
result in innocent lives being lost, and in some circumstances
may result in your liability for these deaths.”
“IT IS UNLAWFUL TO STORE OR KEEP A FIREARM,
RIFLE, SHOTGUN OR MACHINE GUN IN ANY PLACE
UNLESS THAT WEAPON IS EQUIPPED WITH A
TAMPER-RESISTANT SAFETY DEVICE OR IS STORED
OR KEPT IN A SECURELY LOCKED CONTAINER.”

New Jersey:
“IT IS A CRIMINAL OFFENSE TO LEAVE A LOADED
FIREARM WITHIN EASY ACCESS OF A MINOR.”
New York City:
“THE USE OF A LOCKING DEVICE OR SAFETY LOCK IS
ONLY ONE ASPECT OF RESPONSIBLE WEAPONS
STORAGE. ALL WEAPONS SHOULD BE STORED
UNLOADED AND LOCKED IN A LOCATION THAT IS
BOTH SEPARATE FROM THEIR AMMUNITION AND
INA CCESSIBLE TO CHILDREN AND ANY OTHER
UNAUTHORIZED PERSONS.”
North Carolina:
“IT IS UNLAWFUL TO STORE OR LEAVE A FIREARM
THAT CAN BE DISCHARGED IN A MANNER THAT A
REASONABLE PERSON SHOULD KNOW IS ACCESSIBLE
TO A MINOR.”
T
exas:
“IT IS UNLAWFUL TO STORE, TRANSPORT, OR
ABANDON AN UNSECURED FIREARM IN A PLACE
WHERE CHILDREN ARE LIKELY TO BE AND CAN
OBTAIN ACCESS TO THE FIREARM.”
Wisconsin:
“IF YOU LEAVE A LOADED FIREARM WITHIN THE
REACH OR EASY ACCESS OF A CHILD YOU MAY BE
FINED OR IMPRISONED OR BOTH IF THE CHILD
IMPROPERLY DISCHARGES, POSSESSES, OR EXHIBITS
THE FIREARM.”
***************** *****
Please check with your licensed retailer or state police for
additional warnings which may be required by local law or
regulation. Such regulations change constantly, and local
authorities are in the best position to advise you on such legal
matters.

This firearm was originally sold
with a key-operated 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
it can possibly 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. Guns should be
securely stored unloaded, in a
secure location, separate from
their ammunition.
See “Storage Warning”, page 18.
NEVER INSTALL
LOCKING DEVICE
INSIDE TRIGGER GUARD
WHY ARE WE INCLUDING A FIRED CARTRIDGE CASE
WITH EVERY RUGER PISTOL AND REVOLVER?
Certain states and jurisdictions now require that all newly manufactured pistols
and revolvers must be accompanied by a cartridge case, which has been test fired
from that gun at the factory. The case must be placed in a sealed container
bearing certain information concerning this test cartridge.
At the time of retail sale in those jurisdictions, firearms dealers must forward
such test cartridge to a designated destination such as their State Police
Laboratory. As independent Ruger Distributors have nationwide markets without
territorial restrictions, we have decided to include a fired cartridge case with all
new Ruger pistols and revolvers, to minimize the possibility of inadvertent noncompliance with these laws.
Retail customers located in other states, where laws or regulations do not require
the dealer to so act, may be assured that the fired cartridge case they receive with
the firearm at the time of retail purchase is proof that your new Ruger firearm
has undergone our normal test firing procedures during manufacture.

FIREARMS SAFETY-YOUR RESPONSIBILITY
SAFETY MUST BE THE FIRST AND CONSTANT
CONSIDERATION OF EVERY PERSON WHO
HANDLES FIREARMS AND AMMUNITION.
This Instruction Manual is designed to assist you in learning how to use and care
for your RUGER
®
GP100®revolver properly.
Only when you are certain you fully understand the Manual and can properly
carry out its instructions should you practice loading, unloading, etc. with live
ammunition. If you have any doubts about your ability to handle or use a
particular type of gun safely, then you should seek supervised instruction. Such
personalized instruction is often available from gun dealers, gun clubs or police
departments. If none of these sources can help you, write to the National Rifle
Association, 11250 Waples Mill Road, Fairfax, VA 22030-7400. They will put you
in touch with a source of personalized instruction.
The person possessing a gun has a full-time job. You cannot guess; you cannot
forget. You must know how to use your firearm safely. Do not use any firearm
without having a complete understanding of its particular characteristics and
safe use.
Remember: There is no such thing as a foolproof gun.

FIREARMS ARE DANGEROUS WEAPONS–
READ THE INSTRUCTIONS AND WARNINGS IN THIS
MANUAL THOROUGHLY AND CAREFULLY BEFORE USING.
GENERAL INFORMATION
AND MECHANICAL CHARACTERISTICS
The RUGER®GP100® revolver is a double-action firearm which is
specifically designed for heavy Magnum cartridges and embodies many features
found in the famous RUGER
®
REDHAWK®and SECURITY-SIX
®
revolvers. It is the first of an entirely new generation of Ruger double-action
revolvers. The unique frame extension permits the use of full wrap-around style
grips of any desired configuration. This feature reduces overall weight and
contributes to a desirable muzzle of heaviness. The crane and cylinder assembly
of the GP100 revolver locks directly into the frame, both at the rear of the
cylinder and at the front of the crane. The ejector rod serves only as an ejector –
it does not rotate with the cylinder. All of this mechanism is readily removable
without tools and dismantles, along with the cylinder/crane group, into a small
number of subassemblies for inspection and cleaning (See Figure 2, p. 9).

THROUGHOUT THE MANUAL.
!
The internal parts are installed either through the top or bottom of the gripframe; therefore, no side plate is needed. The resulting double solid frame
contributes greatly to the extraordinary strength and reliability of these
revolvers.
The RUGER
®
GP100® revolver has a transfer bar which is connected directly
to the trigger. The transfer-bar safety system provides that the hammer blow can
be transmitted to the firing pin only when the trigger is pulled all the way to the
rear. This is a positive internal safety feature.
Figure 2.
NOMENCLATURE
Figure 1.
Despite their many highly desirable features, Ruger revolvers–as with all
firearms–must at all times be handled with strict attention to correct safety
practices, and be inspected frequently to assure the gun is working properly.

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
AMMUNITION
RUGER®GP100® revolvers will chamber the .357 Magnum, .38 Special +P,
.38 Special +P+, and the .38 Special cartridge. Ruger revolvers are designed for
use with cartridges of the correct caliber which are manufactured in accordance
with the U.S. Industry Standards. Be certain to use proper cartridges of the
correct caliber. See “Care and Cleaning,” p. 19, for important information on
chamber cleaning.
WARNING –AMMUNITION
AMMUNITION (CARTRIDGES) NOTICE
WE SPECIFICALLY DISCLAIM RESPONSIBILITY FOR
ANY DAMAGE OR INJURY WHATSOEVER OCCURRING IN
CONNECTION WITH, OR AS THE RESULT OF, THE USE IN THE
GP100 REVOLVER OF FAULTY, OR NON-STANDARD, OR “RE-
MANUFACTURED”, OR HAND LOADED (RELOADED) AMMUNITION,
OR OF CARTRIDGES OTHER THAN THOSE FOR WHICH THE
FIREARM WAS ORIGINALLY CHAMBERED.
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. Have
adequate ventilation at all times. Wash
hands thoroughly after exposure.
SHOOTING OR CLEANING GUNS
MAY EXPOSE YOU TO LEAD
!

HANDLING
CARRYING: The GP100 revolver can be carried with all chambers loaded. When
the hammer and trigger are fully forward, the transfer-bar is lowered out of its
firing position and the hammer rests directly on the frame.
WARNING –HANDLING
If the trigger is held to the rear, the gun
can fire if the hammer strikes the
transfer bar. Note that it need not be a
deliberate effort to pull the trigger. Any
situation where the trigger attains its
rearward position and permits the
transfer bar to be interposed between the
hammer and the firing pin can cause the
cartridge under the firing pin to
discharge.
NEVER DROP OR STRIKE THE
REVOLVER – COCKED OR UNCOCKED
CARRY AND HANDLE THE REVOLVER
IN SUCH A MANNER THAT THE
HAMMER AND TRIGGER WILL NOT BE
STRUCK.
NEVER CARRY ANY
REVOLVER WITH THE
HAMMER COCKED OR THE
TRIGGER HELD TO THE REAR
DRY-FIRING
“Dry Firing” is practicing the trigger pull of the empty revolver for practice and
familiarity. The GP100 revolver can be dry-fired without damage to the firing pin
or internal components.
Be sure that the revolver is unloaded before handling. Be sure of your bullet
stop, even when dry-firing for practice. Do not dry-fire the revolver with the
plastic ‘safety disc’ on the cylinder.

FIGURE 3
LOADING THE
REVOLVER.
TO LOAD AND FIRE
Be sure the revolver is pointed in a safe direction and is
never cocked while loading.
1. Press the crane latch and guide cylinder out of frame to the left to its loading
position (See Figure 3).
WARNING –CYLINDER INTERLOCK
➧
When correctly operated, the cylinder
cannot be opened when the hammer is
cocked, and the hammer/trigger
mechanism is not able to be operated
until the cylinder is locked shut.
However, this safety interlock can be
intentionally defeated if the crane latch is
depressed and the hammer is then
cocked while the cylinder opened. If the
cylinder is then shut when the hammer
is cocked, the hammer may fall and the
gun may fire.
NEVER CLOSE OR OPEN
THE CYLINDER WHILE
THE HAMMER IS COCKED
2. Insert cartridges and gently close cylinder, making sure it is securely latched.
Do not “flip” the cylinder open or shut.
!
13
5. DO NOT HOLD THE REVOLVER BY THE BARREL OR CYLINDER WHEN
FIRING.
CAUTION–DOUBLE ACTION FIRING
When firing in the double action
mode, be sure that the trigger is
released completely to its fully
forward position before pulling the
trigger for a subsequent shot. If
the trigger finger is allowed to
interfere with the full recovery of
the trigger (preventing it from
moving through about the last
one-eighth inch of its forward
movement), the trigger cannot be
pulled again for another discharge.
The trigger must be fully released
after each shot is fired. This
characteristic is found in all
modern double-action revolvers
and “double-action only” pistols.
FULLY RELEASE
TRIGGER
BETWEEN SHOTS
3. The revolver is now ready to fire, either “double-action” by pulling the trigger
through its complete arc for each shot, or “single-action” by cocking the
hammer and then pulling the trigger for each shot. The trigger pull is
somewhat shorter and lighter when the revolver is fired single action, and
this is the preferred mode for precise shots or target shooting
4. DO NOT TOUCH THE TRIGGER UNTIL YOU ARE READY TO FIRE.
