I consistently carry these 2 models as my only ccw options. I actually lean a little more towards the USP for several reasons. The grip on the HK45 can rub the skin a bit if you iwb carry. And the USP holds 2 more rds, and I'm not big onto carrying extra mags on a regular basis. Either gun is a great option, and way to go ignoring the god forsaken pocket pistol craze.
