HK USP Compact in .40 S&W.

Good capacity (11+1), compact, multiple firing modes, accurate.

From your choices, Sig. Spendy, but dependable.

The grip angle on the Glock is more extreme than I like.

I like the .45 ACP Colt, but the 7+1 and large size turn me off. Now if you were talking Para Ordinance .45's, I'd choose that over anything. Not the P-10, but the next size up, in the LDA.
