The USP is a nice pistol. I have two in .40S&W. I prefer my .45ACPs in 1911 form but do love my Sig P220 too. The only think I dislike about the USP is the proprietary rail but I get around that with a GG&G rail adapter.
Darwin: Love those grips on your Wilson Combat. They look like Lazza's Horned Lizards. Those are probably the next set going on my Kimber Custom II.
Here's a shot of my Springfield 1911. I shot some photos yesterday. I'm not quite there on my settings but getting close.
