Absolutely love the LEM in my USP compact 9mm. It has more use than my USP 9 tactical, therefore has a better trigger. It has the same pull weight as my tactical that has full match trigger parts.
Tried out the LEM in the tactical but preferred the match trigger in that particular gun because I shoot it at distance. In the compact, however, I wouldn't change the LEM for anything - even for a match trigger. Completely love the feel of it in that gun.
