If you have to ask, you have a lot of reading to do. I'd strongly suggest getting - at the very least - a copy of Jerry Kuhnhausen's "Colt 45 Automatic" Vol 1.So would i be better of getting the frame from SARCO and the internals from brownells,midway? What tools should i need? I ordered the punch set from Brownells, im sure i need files what kind of files does anyone suggest? do i need a sear jig or can i buy the trigger kits and have them work?
