The fire control mechanism includes a trigger housing which is fixed to the breach end of the barrel and a trigger which is mounted for pivoting movement between a cocked position and a firing position. The sear is also mounted on a housing for pivoting movement between a striker holding position and a striker release position. The sear is effective to hold the striker in its cocked position and is, in turn, held in its regular holding position by the trigger. When the trigger is moved to its firing position, the sear is no longer supportive by the trigger and no longer able to hold the striker in its cocked position against the biasing means for the striker, which results in the movement of the striker toward its firing position. A locking mechanism is mounted on a trigger housing for selective actuation between an active state and an inactive state. When the locking mechanism…
