ABSTRACT:
A striker-fired firearm with lockable manual safety and method of use. The firearm in one embodiment includes a frame, a chamber for receiving a cartridge, a striker movable to strike the cartridge, a trigger movably mounted to the frame, a trigger bar coupled to the trigger and operable to engage and release the striker to discharge the firearm, a manually-operated safety adapted to engage the trigger bar and selectively movable between a first deactivated position and a second activated position wherein the safety engages the trigger bar to prevent release of the striker, and a cylindrical locking member rotationally disposed in the frame. In one embodiment, the locking member, which may be a lock pin in some embodiments, includes a blocking surface that is engageable with the safety. The blocking surface is rotatable to a blocking position wherein the safety cannot be moved from the second activated position to the first deactivated position by a user. In one embodiment, the blocking surface projects into a slot and engages a protrusion on the safety to block the movement of the safety. Preferably, the locking member is key-operated.
