Not a big fan of the three I've shot (9mm, .45, .40). Glocks and M&Ps are much nicer in my hand, the XD always feels imbalanced (too top-heavy for me, as are H&Ks - Sigs are in between).
And my new(to me) Springfield Loaded 1911 9mm is about the nicest gun I've ever shot. Trying to figure out how to justify the cost for a commander-length Nighthawk in 9mm, it would be just about perfect for extended shooting and classes.
