Had a USP fullsize .40 variant 1 back in '03: The trigger pull was fine, its DA pull was similar to the M9 and its SA pull had no excessive creep or slack. The trigger itself felt like cheap plastic but was contoured nicely Well balanced, and i LOVE european style mag releases, the safety was 1911 inspired so another plus. no slide mounted reversed safety like on a walther pp or beretta 92. was finicky on ammo. I ended up selling mine because i bought it as a SHTF pistol but it refused to cycle steel case ammo at all, and only functioned marginally with anything that wasnt pure factory brass cased ammo. never ran reloads through it because i wasnt into reloading back when i owned it. my bottom line was that it was an excellent duty gun for a cop or civvie (that wanted to deal with that size gun) but as a military arm expected to shoot a range of ammunition from pristine to surplus, it was not gonna work. Glock was a better option at half the price and better performance in that regard. I do own an HK VP9sk which i absolutely love though so its not as if i harp on HK. i just think the USP is an overpriced 'hanger queen' to borrow from my AF lexicon.
