I just got my HK USP45 today, man is this thing nice.  I let my brother talk me out of my Kimber Custom Classic.  There was nothing wrong with the Kimber, I just wanted a DA 45 (I will get another 1911 in the future).  I went to the gun store with the ideal to get a Sig 220, but then I compared the 220 with the HK and really fell for the HK.  It seemed to fit my hands well even though my hands aren't large.  The 10 rnd mag was nice too.  I had read that some sig 8 rnd mags weren't reliable (I read that in several places like the Sig Forums) so that was probably what got me to lookin' at the HK.  Anyway, I really love the gun and would like to hear some other opinions of the USP45.
