My brother is dead set on .45 ACP as his first CCW. Not that there is anything wrong with that but I've explained to him that it limits the available models to choose from. He's leaning towards Glock 36, I'm trying to convince him to try the XD-S for maximum carry-ability. What other models might we be overlooking here? I know there is the M&P 45c, Kahr has at least one slim .45, but what else? I also tried to tell him not to get too hung up on it because he'll be switching models a few times anyways.
