Question about trigger on HK USP 9mm pistol. In my favorite gun store I handled several HK pistols. All but one had a really nice trigger pull, but the one USP 9mm had such a beastly heavy pull on DA I absolutely could not pull that tirgger!! Was something wrong with it? Or is that the way the "standard" USP comes? Their customer service says they can "drop in" a different trigger with a lighter pull, but at extra cost. What goes with that very heavy trigger pull???
