I'd get a Glock 17 over the 45ACP counterpart anyday. Those 45's have way to big of a grip for me and feel real clunky. With modern 9mm ammo you would plenty of defensive power should you need it. You'll shoot the 9mm more. The G22's are cool too but 40's aren't as much fun. You could use that G17 along with some mouse loads and be real competitive in an IDPA match if you ever got into that.
