Abstract: An unfinished firearm frame having a top adapted to receive a slide. Where rear restriction protrusions extend from the top of the frame near a rear of the frame which restricts addition of the slide to the frame and front restriction protrusions extend from the top of the frame and forward of the at least one rear restriction protrusion which restricts addition of the slide to the frame. Where there is a recoil assembly block adapted to prevent a recoil assembly from being assembled into the frame. A jig having a right side and a left side to receive and clamp the frame. The jig including three pin hole guides, a removal guide edge for each of the at least one rear restriction protrusion and the at least one front restriction protrusion and a recoil assembly cutout to allow a tool to pass to the recoil assembly block.
