Firing a revolver with oil, grease, or any other material even partially obstructing the bore may result in damage to the revolver and injury to the shooter and those nearby.

Do not spray or apply lubricants directly on ammunition. If the powder charge of a cartridge is affected by the lubricant, it may not be ignited, but the energy from the primer may be sufficient to push the bullet into the bore where it may become lodged. Firing a subsequent bullet onto the obstructed bore may damage the revolver and cause injury to the shooter and those nearby. Use lubricants properly. You are responsible for the proper care and maintenance of your firearms.





Do not keep your revolver in a leather, fabric or canvas holster when it is stored. These materials attract moisture, even though the holster may appear to be perfectly dry.


With the muzzle pointed in a safe direction, press the cylinder latch and swing the cylinder outward. Check to be sure that each chamber is completely unloaded! With a coin or screwdriver, unscrew the grip panels and remove the grips. Cock the hammer and then insert the disassembly pin into the hole at the bottom of the mainspring strut. Uncock the hammer, remove the hammer strut from the frame, remove the hammer pivot from the frame, and lift the hammer out of the top of the frame. Use a screwdriver to depress the trigger housing latch and remove the trigger assembly from the bottom of the frame.

Store the hammer and the trigger assembly in different locations from the frame. When disassembled in this manner, the revolver is inoperable. It is impossible to fire the revolver until the trigger assembly and the hammer have been correctly reassembled into the frame.

Ruger Lifting Devices

To reassemble the revolver for firing, carefully reinsert the trigger housing into the frame. Place the hammer into the top of the frame, and reinsert the hammer pivot pin. Cock the hammer, reinstall the mainspring strut, and remove the disassembly pin from the mainspring strut. Lower the hammer and replace the grips on the revolver. The revolver is now reassembled and can be loaded and fired normally.

While the revolver is less likely to be used by unauthorized persons when disassembled in the above manner, it is always safest to store a firearm with the supplied locking device correctly installed, or to store the firearm in a gun safe or other secure location, away from children and unauthorized adults. Guns should always be stored securely, unloaded and separate from their ammunition.


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. For increased safety, firearms should be stored unloaded and locked in a location that is both separate from their ammunition and inaccessible to children and any other unauthorized person.



Revolvers made of stainless steel are more resistant to corrosion than blued steel revolvers. However, in the interest of proper operation and long life of your revolver, inspect it frequently and clean, lubricate and apply an appropriate rust preventative.

Sometimes surface discoloration may be noted, particularly in the grip area of stainless steel revolvers, resulting from perspiration. Contact with some types of holsters can also cause stains or rusting. Rusting may also occur as a result of the revolver being exposed to moisture, humidity, salt air or chemicals.

Minor discoloration can usually be removed by rubbing the stained area with an abrasive ink eraser, crocus cloth, or a "metal polishing" compound. When using any of these abrasives, proceed with care and use light pressure to achieve a blending of 'color' with those areas that are not discolored.

External surfaces of the barrel, frame and cylinder should be cleaned and wiped dry after use or after exposure to adverse conditions. If the revolver is to be stored, coat it with a light film of oil or preservative. Where the revolver is in continuing use, and the presence of oil or grease would be objectionable, then the external surface can be coated (after cleaning and drying) with a paste wax formulated for use on metals. Apply the wax sparingly, allow time for it to dry hard, then buff lightly with a soft cloth. When applying the wax, take care that it does not get into the mechanism or on the functioning parts such as the hammer, trigger, crane latch, etc. A properly applied hard wax coating will not interfere with gun handling and it will provide a measure of protection.

The SP101 .38 SPL, .357 Mag. & 9mm revolvers are provided with fixed sights. To change the front sight, drive out the pin in the barrel rib with a small punch and lift out sight blade.
