I was cleaning my USP earlier and noticed the trigger bar appears loose. Specifically, it seems to almost come unattached to from the trigger itself. I never noticed this before so am unsure if it's normal or if I should send it in for repair? See the link above. Also, I know trigger bars aren't supposed to be unmovable, but it seems like mine has a lot more play than normal. And the gap that opens/closes where the bar connects to the trigger isn't something I've ever noticed before in any other firearm.
