Abstract:
1. A firearm comprising: a frame; a firing mechanism disposed in the frame and having a sear and a trigger bar for actuating the sear, said trigger bar having a pivot point and being laterally deflectable for disengagement from the sear; and a locking mechanism cooperative with the trigger bar and configured for actuation from an exterior of the frame for selectively disengaging the trigger bar from the sear; wherein said locking mechanism includes an axially rotatable pin portion having a cammed surface at a distal end thereof; and wherein rotation of the pin portion towards a locked position brings the cammed surface into abutment with the trigger bar, further rotation of the pin causing the cammed surface to exert a lateral force on the trigger bar to laterally deflect the trigger bar out of engagement with the sear, without rotation of the trigger bar about its pivot point.
