Hey guys is it true you can take a stock .40 m&p and simply swap a 9mm mag and a 9mm barrel into it and shoot 9mm ? I have seen a few people mention this but just wondering if i can and should do this. If so, where is a good place in canada to get a barrel ? Tried asking questar but they don't have it and brownells have them, but if you buy from them the state dept. requires a license to get one here. Anyone done this at all ? Is it too much BS ? Thanks.
