I'm going to buy a 9mm pistol for CCW (don't want to get into reasons why i think this is the best caliber for me). Was interested in hearing what people carry and what is the most concealable, in what sort of holster. I would love a springfield xd sub-compact but I don't have any plans of leaving ma anytime soon and i hear they're pretty hard to come by. glock 26? p239? cs9? p99?
