ABSTRACT:
A locking plunger which is perpendicularly movable relative to the direction of movement of the firing pin allows or prevents the axial movement of the firing pin to fire the gun. This locking plunger is spring biassed to abut a safety lever which is part of the sear of the operating members of the gun. The safety lever is located and arranged such on the sear that it allows a movement of the locking plunger into the firing pin unlocking position upon the operating members of the gun reaching the end of the trigger slack. Accordingly a movement of the locking plunger into the unlocking position will proceed not earlier than the sear snapping into the firing position. Any other accidental limited movements of the operating parts of the gun including such of the hammer cannot cause an axial movement of the firing pin because such movement is positively prevented by the locking plunger. Therefore, an accidental firing of the gun is positively prevented.
