Never rely upon any safety mechanism or mechanical device to justify unsafe or careless handling of a firearm. When securing your revolver 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® NEW VAQUERO® revolver also is equipped with a manually operated internal lock. When actuated, this internal lock will secure the hammer in the uncocked or "full down" position.
Before activating the internal lock on your revolver, first visually inspect the chambers to verify that they are empty and do not contain any cartridges.
To activate the internal lock, make sure that the revolver is pointed in a safe direction and that the hammer is in the full down position. Using a small scewdriver, remove the screw securing the grip panels and remove the right grip panel to expose the internal lock. (See "Internal Lock," p. 11.) Insert the key into the keyway and rotate the key fully clockwise (about 180° from the fully unlocked position) until it stops. (See Figure 2.) After you have fully rotated the key 180° clockwise until it stops, remove the key and verify that the internal lock is engaged by attempting to cock the hammer. If the internal lock is engaged, you will not be able to cock the hammer.
To deactivate the internal lock, place the internal lock key into the internal lock keyway (see "Internal Lock," p. 11) and rotate the key counter-clockwise (about 180° from the fully locked position) until it stops. (See Figure 2.)
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.
