Warning Locking Devices

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 23.

GENERAL INFORMATION AND MECHANICAL CHARACTERISTICS

The RUGER® SP101® revolver is a double-action firearm which embodies many features found in the famous RUGER® GP100® and RUGER® SUPER REDHAWK® 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 SP101 revolver lock directly into the frame, both at the rear of the cylinder and at the front of the crane. The ejector 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 1).

The internal parts are installed either through the top or bottom of the grip-frame; therefore, no side plate is needed. The resulting double solid frame contributes greatly to the extraordinary strength and reliability of these revolvers.

The RUGER® SP101® 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.

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.

A 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

AMMUNITION

RUGER® SP101® 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 page 21 ("Care and Cleaning") for important information on chamber cleaning.

Please refer to the Notes below regarding proper ammunition for the available SP101 calibers.

Notes on Caliber .38 Special: .38 Special caliber revolvers are designed specifically for modern higher-powered factory loaded cartridges, including .38 Special and .38 Special + P ammunition.

Notes on .357 Magnum caliber: This revolver is designed to fire factory loaded .357 Magnum, .38 Special and .38 Special + P ammunition.

Special Ammunition Notice for .357 Revolvers marked "125 GR. BULLET" only: Some revolvers have slightly shorter cylinders and frames and are therefore limited to the use of .357 Magnum ammunition with a maximum bullet weight of 125 grains and an overall loaded cartridge length of not more than 1.57 inches. These revolvers are roll-marked with "125 GR.BULLET" on the right side of the barrel.

Ammunition containing heavier bullets or of a longer length may not permit the cylinder to close or rotate! You may not even be able to fire the revolver if you try to use longer or heavier bullets. Be sure the ammunition you wish to use in the revolver will chamber freely, and will permit the cylinder to open, close and rotate readily. Do not assume any ammunition will work without checking it first.

All other .357 SP101 revolvers can use all standard factory .357 loads.

Notes on 9mm Parabellum Revolvers: This model is chambered for the 9mm Parabellum (Luger) cartridge. A package of 9mm clips are supplied with the revolver and are required to allow proper ejection of the 9mm rimless cases. See SPECIAL INSTRUCTIONS FOR 9mm CLIPS, p. 14. Do not use any other 9mm cartridges (9mm Short, 9mm Bergmann, etc.).

Because 9mm cartridges are manufactured worldwide for use in pistols, revolvers, and submachine guns, it is possible to encounter cartridges which, when fired, develop pierced primers. If this occurs, discontinue the use of the particular brand or type of ammunition. The possibility of a pierced primer is another complete reason why a shooter should always wear protective glasses to shield his eyes. Use only metal jacketed bullets in 9mm revolvers. When a lead bullet is fired, its base expands and a ring of lead is shaved off and deposited in the shoulder area of the chamber. A build-up of lead rings can prevent proper chambering of cartridges because 9mm cartridge mouths seat on the chamber shoulders.

Notes on .22 Caliber Long Rifle: The .22 cal. model is a six-shot double action revolver chambered for the .22 Long Rifle cartridge. The .22 Short, .22 Long and .22 shot cartridges can also be fired from this model. It should be noted that extensive use of the .22 Short cartridge can cause a "ring" to be cut in each cylinder chamber which may interfere with the extraction of Long and Long Rifle Cartridges.

Notes on Caliber .32 H & R Magnum: This six-shot SP101 chambered for the Caliber .32 H & R Magnum cartridge will also chamber the .32 S & W cartridge and the .32 S & W Long cartridge. The use of other than .32 H & R Magnum cartridges, may, in some loadings, result in unsatisfactory accuracy.

For reasons noted above, revolver chambers should be cleaned regularly and chamber cleaning should be the first corrective action when cartridges of the correct caliber and type do not chamber properly.

A WARNING-AMMUNITION

i/2

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 (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 SP101 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.

OPERATION OF "DOUBLE-ACTION ONLY " REVOLVERS

(This section applied only to "Double-Action Only" revolvers, identified by their lack of a hammer spur)

The model you have selected is equipped with a special trigger mechanism that permits only "double-action" firing. The hammer cannot be manually cocked, since there is no full cock notch or hammer spur. The revolver can only be fired by a relatively long ("double-action") pull of the trigger which draws the hammer rearward and then releases it to fire every shot.

It is important to note that the mechanism of the gun will not permit another shot to be fired unless the trigger is first fully released and then pulled again.

The revolver has an internal transfer bar that will not allow the hammer to contact the firing pin and fire the gun until the operator completely pulls the trigger.

A WARNING-DOUBLE-ACTION ONLY

Do not attempt to manually cock the hammer! Since there is no full-cock notch, the hammer will fall forward when released, and if finger pressure is applied to the trigger, the revolver can fire. The automatic safeties that prevent firing if the hammer falls are deactivated if the trigger is pulled. Do not touch the trigger unless you intend to shoot the revolver!

DO NOT COCK HAMMER

A CAUTION: When firing the double-action only revolver, là be sure that the trigger is released completely to its fully forward position before attempting to pull 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), pulling the trigger will not fire the revolver. The trigger must be fully released after each shot is fired. This characteristic is found on all modern double-action revolvers and "double-action only" pistols.

HANDLING

CARRYING: The SP101 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.

A WARNING-HANDLING

s

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 SP101 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.

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, below).

LOADING THE REVOLVER.

2. Insert cartridges and gently close cylinder, making sure it is securely latched. Do not "flip" the cylinder open or shut.
