Instruction manual

Always unload a firearm

before cleaning, lubrication,

disassembly or assembly.

2. Insert a blunt, ‘pointed’ instrument in the oval recess of the mainspring

housing (at the back of the grip) and swing the housing latch open like the

blade of a pocket knife. (Some users find that a paper clip, looped over the

latch, is an ideal ‘instrument’ for this phase of disassembly.)

3. Swing the entire housing outward on its pivot and pull downward, removing

the mainspring housing and bolt stop pin. With new pistols it may be

necessary to lightly tap (with a plastic hammer and wooden dowel) on the

top portion of the bolt stop pin—which protrudes above the receiver—while

pulling downward on the mainspring housing. Be careful not to damage the

rear sight.

4. Fully insert the empty

magazine into the frame. Point the muzzle upward in

a safe direction and pull the trigger rearward. The bolt will drop out of the

receiver or it can readily be removed. Remove the magazine.

5. With the mainspring housing, bolt stop pin, (as an assembly), bolt and

magazine removed, a forward blow (with a plastic hammer) on the rear of

the receiver will disengage the barrel-receiver assembly from the grip frame.

No attempt should be made to remove rivets or staked pins. Further

disassembly should be undertaken only by the factory.

REASSEMBLY

(The procedure is the same for all RUGER

MARK III pistols.)

1. Be cer

tain the pistol is free of

cartridges! The safety must be

in the "off" (F) position for

reassembly.

2. Keep your finger off the

trigger. Place the hammer in

the horizontal (cocked) position.

(The hammer is visible by

looking down on the grip frame

and is the rectangular object

inside the grip frame and near

the rear. See Figure 6.)
