ABSTRACT:
A rotatable shaft member supports a first control member and a second control member. The first control member cooperates with a tang of a rotatable sear. The second control member cooperates with an abutment stop of the sear. When the shaft is rotated to where the second control member contacts the abutment stop of the sear, the sear is blocked and the gun cannot be fired. When the shaft member is rotated such that the second control member is moved away from the tang of the sear, the gun can be fired. When the shaft member is rotated further such that the second control member is remote from the abutment stop and the first control member contacts the tang of the sear, the tang moves out of contact with the searing surface of the hammer. The hammer begins to pivot in a gun firing direction until the tang engages a half-cocked notch for stopping movement of the hammer, whereby the hammer is decocked.
