ABSTRACT:
A portable firearm employs a frame and an upper mechanism having a bolt and a sliding hammer. A barrel assembly is supported on the frame and has an axis, a muzzle and a breech. The sear transversely straddles the barrel assembly and can project above its axis for restraining the hammer. A trigger mechanism employs a reciprocatable member coupled to the sear for selectively operating the sear automatically or semi-automatically. An intervening member is mounted to reciprocate transversely to the axis of the barrel assembly. This intervening member can retract upon the hammer moving against the intervening member. The intervening member is bifurcated to straddle and reciprocate transversely to the axis of the barrel assembly.
