Abstract

A semi-automatic pistol has a frame having a trigger guard defining a trigger finger space, a barrel connected to the frame and defining a bore axis, a slide connected to the frame and operable to reciprocate along the bore axis between a forward battery position and a rearward open position, a recoil mechanism operably connected between the slide and the frame, and operable to bias the slide to the battery position, and the recoil mechanism being entirely below the barrel axis and forward of the trigger finger space. The recoil mechanism may be a recoil spring defining a spring axis. The spring axis may be parallel to the bore axis. The recoil spring may be a helical shape defining a bore receiving a guide rod. The guide rod may be below the barrel. The trigger guard may have a downwardly facing upper surface defining the trigger finger space.

Abstract

A rotational sear block isolates the rotational movement of the sear to the sear mechanism without using a rotational trigger. The isolation of the sear rotation to the sear mechanism allows for a single axis translational trigger to be used which gives the shooter the advantages of a short, crisp trigger pull without any off-axis movement. Additionally, the positive sear engagement and inherent safety of the design are achieved due to the sear being engaged and biased onto the sear block surface, disallowing unintended or accidental release.
