With th LEM trigger they are ok. The standard DA/SA trigger is just craptastic.
I like the compact better than the fullsize. Mostly due to the weight of the slide. Much heavier than it needs to be. Mass is good for recoil dampening, but not when it is reciprocating mass. Also, two stage recoil springs are more common on compacts, so you can't be as picky about the weird sight movement during rapid fire caused by it. Then there is the high bore axis. I'm in the vast minority with regard to the mag release as I can reach it with my strong hand thumb just fine and actually kind of liked the control layout. It did go bang reliably though.
Had a fullsize USP, was my first gun. Got rid of it now that I know better. If they were cheaper, i'd consider one with a LEM trigger. But at their current prices, I would go elsewhere.
