H&K USP 9mm LEM trigger modifacation.

[Olddude]

I traded for this yesterday for another H&K. The other one had a LEM also but it must have been the light because it was much lighter (duh). I know I can change the springs and that will give me a trigger I can live with. This is just a range piece. My question is what all is involved with installing a match trigger. I ask this because of no safety and decocker. This might be a dumb question that is self explanatory but there is not much info on switching from a LEM.
Thanks!

I think you will also have to buy a saftey lever assembly.
