H&K USC .45 ACP. This little gun is really, really fun to shoot. So far it feeds everything I pump through it without a hiccup. At moderate ranges it is amazingly accurate. The only drawback I can see is the 10 rd. magazine. I know it can be converted to take 30 rd. grease gun mags, but I will probably just leave it alone. Here in MA we still have the high cap ban anyway. This may well become my home defense carbine.
