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: ! WARNING ! ADVERTENCIA “A los niños los atraen las armas de fuego y las pueden hacer funcionar.
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.
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 INACCESSIBLE TO CHILDREN AND ANY OTHER UNAUTHORIZED PERSONS.
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.
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.

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.
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.
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.
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). FIGURE 3 LOADING THE REVOLVER. 2. Insert cartridges and gently close cylinder, making sure it is securely latched. Do not “flip” the cylinder open or shut.
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.
! WARNING–FIRING When firing the GP100 revolver, be sure all persons are a safe distance to the rear of the shooter. When fired, all revolvers discharge hot gas and particles of lead, powder grains, or lubricant through the clearance gap between the cylinder and the rear of the barrel at high speed. This can injure a person who is standing too close to the revolver.
Practice this important gun handling skill with an unloaded revolver until you have developed the proper control and ‘touch’ to decock your revolver safely. The key to safe decocking is having the weight of the revolver controlled with one hand, while the thumb and forefinger of the ‘shooting hand’ control the hammer and trigger. Improperly restraining the trigger during this procedure may result in the hammer not resting fully against the frame.
NOTE: When ejecting fired cartridge cases, position the revolver at a high angle so the cases will come fully out of the chambers and not slip under the ejector. This high angle positioning is not necessary when ejecting unfired cartridges. CORRECT UNLOADING SEQUENCE 2 ! WARNING – DISASSEMBLY 2 Always unload a firearm before cleaning, lubrication, disassembly or assembly. Never remove or install a loaded cylinder – it can fire if dropped or struck.
DISASSEMBLY Read instructions before disassembling a gun. 1. BE CERTAIN THE REVOLVER IS UNLOADED BEFORE DISASSEMBLY. 2. Using a properly fitting screwdriver, remove grip screw. Remove pistol grip inserts from grips. Grip panel locator may then be removed. Pull grip downward off frame. Take care not to lose the disassembly pin, which may fall free when the grip is removed. 3. Cock the hammer. Insert disassembly pin about one half its length into the hole at the rear of the mainspring strut (See Figure 5).
NOTE: If you cannot supply sufficient force to the plunger using the mainspring assembly as a “tool”, then use a screwdriver of appropriate size and insert through hole in frame. It may be necessary to slightly depress the trigger while removing the trigger guard assembly. 8. Cradle the revolver frame in your left hand and with the thumb of your right hand press cylinder latch button, swing out cylinder assembly and remove it forward from the frame. 9.
6. Open and close cylinder. Function the trigger and hammer single action and double action to be certain that all parts are working properly. CARE AND CLEANING ALWAYS BE CERTAIN THE REVOLVER IS UNLOADED BEFORE CLEANING. The internal mechanism of the GP100 revolver can be lubricated without disassembly. A few drops of light oil recommended as suitable for firearms, applied periodically about the various frame openings, will work its way into the mechanism parts.
If lead bullet loads are fired extensively, lead build-up may cause cylinder binding. Lubricate the cylinder crane gap with Break-Free® CLP or some other lubrication which meets mil. spec. Mil-1-63460 to prevent this condition. STORAGE GUNS SHOULD NOT BE STORED LOADED! USE THE LOCKING DEVICE SUPPLIED WITH THE REVOLVER FOR STORAGE. (SEE PAGE 6) Do not keep your revolver in a leather, fabric or canvas holster when it is stored.
! WARNING – STORAGE Never place or store any firearm in such a manner that it may be dislodged. Firearms should always be stored securely and unloaded, away from children and careless adults. Use the locking device originally supplied with this firearm for storage. The use of a locking device or safety lock is only one aspect of responsible firearms storage.
SIGHTS The GP100 revolver is provided with an insert front sight. To change the front sight, depress the spring-loaded plunger in the front of the barrel rib with a small punch and lift rear of sight blade. The adjustable rear sight has a white outline blade. Each click of the rear sight adjustment screws (either windage or elevation) will move the point of impact of the bullet approximately 3/4” at a distance of 25 yards. Move the rear sight in the direction you desire the bullet to move on the target.

THE BASIC RULES OF SAFE FIREARMS HANDLING We believe that Americans have a right to purchase and use firearms for lawful purposes. The private ownership of firearms in America is traditional, but that ownership imposes the responsibility on the gun owner to use his firearms in a way which will ensure his own safety and that of others. When firearms are used in a safe and responsible manner, they are a great source of pleasure and satisfaction, and represent a fundamental part of our personal liberty.
A safe direction must take into account the fact that a bullet may penetrate a wall, ceiling, floor, window, etc., and strike a person or damage property. Make it a habit to know exactly where the muzzle of your gun is pointing whenever you handle it, and be sure that you are always in control of the direction in which the muzzle is pointing, even if you fall or stumble. Keep your finger off the trigger until you are ready to shoot. 3. FIREARMS SHOULD BE UNLOADED WHEN NOT IN USE.
5. BE SURE OF YOUR TARGET BEFORE YOU SHOOT. Don’t shoot unless you know exactly where your bullet is going to strike. Be sure of the bullet stop behind your target, even when dry-firing with an unloaded gun. If you are in the field hunting, do not fire at a movement or noise. Take the time to be absolutely certain of your target before you pull the trigger. 6. WEAR SHOOTING GLASSES AND HEARING PROTECTORS WHEN YOU SHOOT.
8. DON’T SHOOT AT A HARD SURFACE, OR AT WATER. Bullets can glance off many surfaces like rocks or the surface of water and travel in unpredictable directions with considerable velocity. 9. NEVER TRANSPORT A LOADED FIREARM. Firearms should always be unloaded before being placed in a vehicle. A suitable carrying case or scabbard should by used to carry an unloaded firearm to and from the shooting area. 10. AVOID ALCOHOLIC BEVERAGES WHEN SHOOTING. Don’t drink until the day’s shooting is over.
A BRIEF ACCOUNT OF AN EXTRAORDINARY ACHIEVEMENT: RUGER FIREARMS One of the few American firearms manufacturers whose management has remained in the same family since starting in business, Sturm, Ruger & Company, Inc., had its beginning in a small machine shop occupying a rented frame building in Southport, Connecticut. In January, 1949, with an initial investment of only $50,000 and an idea, William B. Ruger and Alexander M. Sturm started production of a .
