New to the forum and have already learned a lot!!! Been lurking for a few months. I finally got rid of my last 1911 and have become a Glock junkie. I have recently purchased a 19 and 17, but I am absolutely fascinated with the 357Sig. I am strongly considering buying a couple barrel conversions, so the question is this. I see how easy and effective it is to go 40 to 357, but what about going 9 to 357??? Looks as simple as buying the barrel and mags? What am I missing since I can't seem to find much if any written about going 9 to 357? Thanx in advance for any tips, tricks and advice?
