Correct Installation of Lock For

Ruger

Mark III & 22/45 Mark III Pistols Only

Use the Correct Lock: While the basic locking device is substantially

similar for all Ruger

firearms, due to the different shapes of the many

Ruger

firearms, some firearms utilize different locking devices. The lock

with a 1 1/2” shackle is for use with RUGER

MARK III

22/45 MARK III Model Pistols. It is very important to use the correct

locking device!

To Install the Factory-Supplied Locking Device:

1. Keep the muzzle pointed in a safe direction and your fingers outside the

trigger guard at all times!

2. Be sure the firearm and its magazine are completely unloaded and

contain no cartridges or cartridge cases! Remove the magazine from your

pistol.

3. Open the action completely. Use the bolt stop to keep the action open

during installation of the locking device.

4. Apply the lock by placing the shackle of the lock into the slot in the bolt

as shown below.

5. Close the lock by pressing the shackle into the body of the lock (the part

that receives the key) as tightly together as possible. The lock has

bumpers that will not harm the metal finish of your firearm; be careful

not to dent the frame or grip panels of the pistol.

6. Once the lock is securely closed, remove the key. Pull firmly on the lock

to test the connection and be sure it is locked. Do not leave or store your

firearm with the key in the lock! Store your locked unloaded firearm and

the key in secure, separate locations, away from ammunition, children, or

unauthorized adults.
