Do yourself a favor and give a look to the Springfield Armory XD series...I've spent some time with the XD40 subcompact (three-inch barrel, .40 cal, double stack, 12 round magazine).
Terrific little brute of a gun that will allow you to shoot surprisingly well with a little practice. Tough like a Glock but the handle is better designed (for me) and it does have the grip safety.
