I agree here. I recently got a Glock 23 and it' s very accurate plus it' s as compact as my .357 S&W-66 snubie. But any compact or mini-auto of good quality should do.
Just make sure you get one that fits your hand good, this is real important on downsized handguns. I would have liked one of the mini Glocks but my big paws won' t fit them right.
