I installed one of these in my USP 9mm. Aside from not having any instructions and trying to figure out what the parts actually were for, it was pretty easy to install.
The pre-travel was reduced by about 1/4 - 1/3. Reset is very short. Overall, pretty happy with the results. The Trigger pull feels about the same, but I already had a match trigger installed. I'm going to put one in my USP in .45.
