I'll take a Glock any day over a H&K. My USP 9 had the worst trigger, I considered myself lucky if I could hit standard 50 foot target with that pistol if I was standing right next to it. And my buddies P-30 had numerous FTF and FTE for the first 500 rounds. And though the pistols reliability has improved it's still not 100%.
Don't blame the gun for the shooter's problems . I shoot my HnK as well as any other gun except maybe my 1911's, even then it's kinda a tossup.
