I was talking to a gun friend of mine the other day and we were stuck on weather the 1911 has a different frame for the 9mm/38 super cals? I know you have to use a different extractor for the 9mm/38 VS 40/45 cals, but I believe a 1911 frame is a 1911 frame reguardless of what caliber you build it to be. What say yall
