Never rely upon any safety mechanism or mechanical device to justify unsafe or careless handling of a firearm. When securing your pistol or to prevent unauthorized access, you should rely first and foremost on the key-operated locking device supplied with your pistol. (See Page 6.) However, for added security, and to comply with certain state and local laws, your RUGER® P345TM pistol is also equipped with a manually operated internal lock. When actuated, this internal lock will secure the manual safety in the "on" or "safe" position.
Before activating the internal lock on your pistol, first visually inspect the chamber and magazine to verify that they are empty and do not contain any cartridges.
To activate the internal lock, first make sure that the pistol is pointed in a safe direction and that the manual safety is in the "on" or "safe" position. With your safety in the "on" or "safe" position, the internal lock keyway is exposed through the hole in the right safety lever. (See "Nomenclature," p. 9.) Insert the key into the keyway and rotate the key fully clockwise (about 90° from the fully unlocked position) until it stops. (See Figure 4.) Only after you have fully rotated the key 90° clockwise until it stops, you should then remove the key and verify that the internal lock is engaged by attempting to move the safety to the "off" or "fire" position. If the internal lock is engaged, you will not be able to move the safety to the "off" or "fire" position.
To deactivate the internal lock, place the internal lock key into the internal lock keyway (see "Nomenclature," p. 9) and rotate the key counter-clockwise (about 90° from the fully locked position) until it stops. (See Figure 4.)
Be sure to store the internal lock key in a secure location, away from children and careless adults. Do not store your firearm with the key in the internal lock keyway. Never lock a loaded gun - always unload the gun before locking.
