Ok, I searched the forums and didn't find an answer for the question that follows. If you know where I can find it in this forum, please link me. Here goes: After some searching, I've heard a couple of different ways I could change my Glock 22 to shoot 9mm. One involves getting a conversion BBL. Now there are two other ways that I read that were possible. One is just using a 9mm BBL and one is just replacing the top (slide and BBL). Which of these latter two are possible AND safe, if either. Just for info purposes, I have both 22 and 17. The 22 is refinished and I'd like to use it more, hence the question. Thanks for any help/advice.
