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

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.
