I too have owned H&k pistol, [usp variant #1 in 45acp] and have nothing but good things to say about it. I sold it, using the money to by another fine combat pistol = Glock [model 20 in 10mm]. Both these weapons have one thing in common = reliability!!
My next purchase [handgun] is going to be another H&K product, a compact usp [variant #1] in 357sig. There pretty hard to find, hoping to find one at the Tulsa gun show.
It's really to bad H&K does not chamber one of there full sized models in 10mm, what a fine weapon that would be!!!
