The early Compact 9mm and .40 cal had some horrible triggers - gritty and heavy. It was improved with the later issue .45 USP Compact. A good polishing of the trigger system in the early models would improve the action.

Secondly, on 2001 Ayoob pointed out that there were some failures to fire using 9mm Winchester White Box in the 9mm USP Compact. Apparently some lubricant got into the firing pin channel which would not allow enough force to light up the Winchester standard pressure round. It only happened occasionally, not all the time. Maybe it has been fixed by now.
