USP 45 or ???

I have been thinking I need to get a pistol I can beat up a little bit. My 1911 is kind of too nice. I would primarily bring it along when hiking or camping, for home defense and of course it would get a workout at the range.

Primarily I want a pistol that is reliable and easy to maintain. I have been thinking full size, and I would like to stick with .45 cal. A decent trigger is important. The more magazine capacity the better. Price is not a big deal but I don't want to get too carried away.

I have been leaning towards a HK USP 45. It seems to be my best bet so far.

I'm not a big fan of the Glock trigger. The Sig 220 is a contender, but it doesn't hold quite as much ammo as the HK.

Is there something else I should consider? I would appreciate any input.
