Unfinished firearm frame and jig
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.
1. A pistol frame workpiece for modification to become a pistol frame configured to receive a slide, the workpiece comprising:
a body having a grip, a trigger guard, and a forward frame portion extending forward of the grip;
the body defining an upper plane surface facing away from the grip and configured to be proximate to a lower surface of the slide;
a receptacle defined by the body and configured to receive a rail component having upper rail elements configured to engage the slide; and
the body including an integral protrusion protruding above the upper plane surface of the body adjacent the receptacle and configured to prevent insertion of the rail component into the receptacle.
2. The pistol frame workpiece of claim 1 , wherein an aperture is defined by the body at the receptacle, the aperture configured to receive a pin engaging the rail component.
3. The pistol frame workpiece of claim 1 , wherein the block element is configured to contact the rail component to deny full insertion of the rail component into the receptacle.
4. The pistol frame workpiece of claim 1 , wherein the forward frame portion has opposed elongated upper edges in part defining the upper plane surface and spaced apart to define an elongated channel having a length and configured to receive an elongated pistol operating component; and further including a web positioned at an intermediate position along the length of the channel, the web spanning between the opposed elongated upper edges to divide the channel into a forward portion and a rear portion, and the web configured to prevent insertion of the elongated pistol operating component.
5. A pistol frame workpiece for modification to become a pistol frame configured to receive a slide, the workpiece comprising:
a body having a grip, a trigger guard, and a forward frame portion extending forward of the grip;
an upper plane surface defined by the body to face a lower surface of the slide; and
a protrusion integral with and protruding above the upper plane surface of the body and configured to limit proximity of the lower surface of the slide to the upper plane surface when present, and to enable proximity of the lower surface of the slide to the upper plane surface when removed.
6. The pistol frame workpiece of claim 5 , wherein an aperture is defined by the body at the receptacle, the aperture configured to receive a pin engaging a rail component.
7. The pistol frame workpiece of claim 5 , wherein the block element is configured to contact a rail component to deny full insertion of the rail component into the receptacle.
8. The pistol frame workpiece of claim 5 , wherein the forward frame portion has opposed elongated upper edges in part defining the upper plane surface and spaced apart to define an elongated channel having a length and configured to receive an elongated pistol operating component; and further including a web positioned at an intermediate position along the length of the channel, the web spanning between the opposed elongated upper edges to divide the channel into a forward portion and a rear portion, and the web configured to prevent insertion of the elongated pistol operating component.
9. A pistol frame workpiece for modification to become a pistol frame configured to receive a slide, the workpiece comprising:
a body having a grip, a trigger guard, and a forward frame portion extending forward of the grip;
the forward frame portion defining an upwardly open elongated channel configured to receive an elongated barrel; and
a web transverse to the channel, dividing the channel into a forward portion and a rear portion, and when the web is present to prevent the insertion of the barrel in the channel and when the web is absent to enable insertion of the barrel in the channel.
10. The pistol frame workpiece of claim 9 , further including a jig, said jig having a right side and a left side to receive and clamp the body, said jig including three pin hole guides, and said jig including recoil assembly cutout to allow a tool to interact with web.
11. The pistol frame workpiece of claim 9 wherein the forward frame portion has opposed sides each terminating at an upper edge, and wherein the web spans between said sidewalls.
12. The pistol frame workpiece of claim 9 wherein the forward frame portion has opposed sides each terminating at an upper edge, and wherein the recoil assembly block is perpendicular to the sidewalls.
13. The pistol frame workpiece of claim 9 wherein the forward frame portion has opposed sides each terminating at an upper edge, and wherein the web has an upper edge at a level above the upper edges of said sidewalls.
14. The pistol frame workpiece of claim 9 wherein the web is a panel having peripheral portions having a first thickness and a central portion having a lesser second thickness.
