Hello, I am looking into building my own 1911 and would like to make a double stack. I have seen the 80% kits for 1911s and even 1 for a 2011 but it includes the frame. I can get a frame but am lost in how to build the rest of it. I have not seen 2011 kits that do not include the frame. I know the frame is wider than a 1911 so what parts can I use from a 1911 or does anyone know of 2011 kits/ item lists that I would need to finish off the build.
