ABSTRACT:
In a semi-automatic firearm is a simplified firing mechanism that includes a manual safety system and a doubly redundant automatic safety system. The firing mechanism includes a trigger, a trigger bar, a trigger lever, a firing pin safety, spring loaded striker with a firing pin, a sear, a dislocator and a manual safety. When the manual safety is in the safe position the striker is blocked and the trigger bar is disengaged from the sear and the dislocator. If the manual safety is in the firing position, but the trigger has not been fully released after each discharge, the trigger lever cannot move the firing pin safety out of the way of the striker, and the trigger bar cannot move the sear.
