Update, ok, just tried it, no way. The original just drops in while the USP is far too big.

I'm thinking that smoothing out that rough area should take care of this issue.
To follow up on this, I smoothed the rough spot on the trigger bar. It feels much better, no real obvious click anymore. It's not quite 100% yet but I'll see how it feels after I shoot it tomorrow.
I'm referring to the step/bur at the bend in the rear, second photo. You can see it in the third pic too. I believe the control latch drags on this section of the trigger bar.
I did a thorough inspection of the internal parts in my P2sk LEM and found after very close inspection similar roughness on the trigger bar ( it would actually move sideways while resetting due to the abnormality), I massaged it as needed, and then very gently smoothed the other fire control parts, hammer, hammer axle, sear axle and trigger axle then had Robar apply Np3+ to all of them it made a noticeable difference. My 45C will be getting the same love soon.

Had the same issue on a USP9 I just got (2007). A false click right before the actual reset, and then it felt like something was hanging up in there. Made slow precise shots difficult. Very annoying. I detail stripped it and noted it had the burr in the same spot. Filed it flush with some needle files, and the issue is 100% gone. I noticed that the catch has some wear marks that became sharp that were not there when I installed the grey guns kit, not sure if this was related or not. I'm happy it's fixed, thanks to everyone who gave advice.
