As some of you may know I've had my USP compact for about 12 years and it's the DA/SA version. Well about 4 years again I got myself a P2000SK with the LEM trigger and fell in love with the trigger. The P2000SK was the LEM heavy but with a couple spring swaps it's now the LEM light and it's IMO the perfect DAO trigger pull. I finally got around to swapping out my USP's DA/SA to the LEM tonight. I've detail stripped many of my other handguns but was kinda scared to detail strip this the USPc. I read the instructions about 50 times plus did quite a bit of reading on HKPro about the conversion and figured I'd give it a shot. It wasn't near as bad as I thought, took me about an hour and I only had it together/apart about 10 times before I got it right. So anyone thinking about doing this themselves, if you're mechanical inclined at all about handguns don't be scared to do this one yourself.
