I've been taking a gander at the HK USP 9mm. I'm not set on the full-size or compact, as this will primarily be a range/home defense gun. The Glock 19 is currently pulling CCW duties, but I'm not opposed to switching it out from time to time with another gun.

So, can someone give me the rundown on the USP/USPc, what the positives and negatives are regarding things like: accuracy, trigger pull, parts and mags, etc.

Or would someone recommend something else all together? I'm mostly looking for something in a DA/SA trigger and would like one of the higher quality makes/models like HK, Sig.
