Abstract: The present invention provides a pistol with a frame having a rear grip, a trigger facility forward of the grip and an upper surface. An elongated slide connects to the frame and is operable to reciprocate along the upper surface. The frame defines a trigger recess open above the trigger facility at the upper surface. An insert has a major portion removably received in the trigger recess and has a rail extending from the major portion above the upper surface. The frame rail is adapted to connect with the slide to constrain reciprocation of the slide.
