Funny...the H&K does poorly in specious, uncontrolled You Tube "torture" tests...and great in actual, controlled, organized military reliability tests.
I was part of a group of eighty guys with brand new H&K USP pistols. We were shooting in the sand, and dust, of the desert on all temperatures. Over 1,200 rounds each, without cleaning or even lubrication during that time. Roughly 100,000 rounds through those H&K pistols.
Not one failure. Not one jam.
As reliable as any pistol ever built.
I got my USP compact, in .40S&W, LE trigger, tritium sights, for $500. Yeah it was a special deal. But I'm glad I have it. It's a great gun. No safety, as a carry gun should be. My only complaint is the heavy trigger pull on the DAO trigger. It comes it at about eight pounds. Some day, I may modify it. After a few thousand rounds, it's a bit smoother, but not much. I like the ergonomics and the fit of the pistol in my hand.
And folks don't care for the H&K magazine release, but I've never seen any H&K magazine come loose during firing because the shooter had a tight grip and inadvertently squeezed the magazine release button.
However, I have seen this happen to 1911s, M&Ps and even Glocks. With a few thousand practice reloads on my H&K, I can hit that button with the middle finger of my strong hand, drop the mag and reload in under a second. The USP Compact is my carry gun and there is no more reliable pistol made.
