ABSTRACT:
A pistol including a mechanism that locks manual safety of the pistol. The lockable manual safety mechanism may include a manual safety that engages the firing apparatus of the pistol to prevent discharge of the pistol when the trigger is pulled. The firing apparatus may include a trigger, trigger bar, sear, and hammer that contacts a firing pin which may strike a chambered cartridge. The manual safety may be movable into and out of engagement with the firing apparatus. In one embodiment, the safety engages the sear to prevent the sear from moving and releasing the hammer while held in the cocked position by the sear. In one embodiment, the manual safety is a lever that is pivotally mounted to the frame of the pistol. The pistol may further include a locking member that engages the safety. The locking member may be movable from an unlocked position in which the manual safety is freely movable, to a locked position engaging the manual safety so that the safety cannot freely move and is locked into engagement with the sear while the hammer is held in the cocked position by the sear. In one embodiment, the locking member may be a lock pin that may be rotatably carried by the pistol.
