KWA USP .45. Great backup for my G3SG/1 in keeping with my H&Ks only policy. Shoots 300-320 FPS on green gas (shots can penetrate both sides of a coke can at almost point-blank range). I use my sidearm more than I have to. The G3 is damn heavy and the USP comes in handy when I need to make speedy flanking assaults. Also, the pistol is extremely useful indoors in an urban venue.
