3 WARNING! “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.” ADVERTENCIA! 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 imeto 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.” 4
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.” 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.” Texas: “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. 5
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 non- compliance 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. !WARNING – LOCKING DEVICES DO NOT INSTALL INSIDE TRIGGER GUARD INSTALL LOCK AS SHOWN HERE 6

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 parts or accessories not made by Sturm, Ruger & Co. Inc. DO NOT ALTER ANY GUN 8 ! ! 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). WARNINGS OF GREAT IMPORTANCE ARE FOUND ON THE FOLLOWING PAGES: Locking Devices 6 Firing 14 Alterations 8 Disassembly 16 Ammunition 10 Lubrication 19 Lead Exposure 10 Storage 21 Handling 11 Parts Purchasers 24 Cylinder Interlock 12 OTHER CAUTIONS AND WARNINGS APPEAR THROUGHOUT THE MANUAL.
The internal parts are installed either through the top or bottom of the grip- frame; therefore, no side plateis needed. The resulting doublesolid 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. 9
10 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
11 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.
