I installed the LEM kit today in my USP 40, took all of 15 min and was super easy. I have tried to sell this kit for a while but after a great article from one of the members here I decided I would throw it in. I'm not sure I like it, in all honesty it kinda freaks me out. It's like a 1911 with no safety and while yeah that's awesome I have used DA/SA for a long time and it's just a new world. Anybody else have the same feeling with it when they switched?
