Seriously considering one of these little puppies. Wondering if I should go LEM or not. I understand the reset is short so at least it's not a long DA pull. Still I'm used to DA/SA because of my USPs (which I will eventually sell off probably). If you have one did you go LEM or not? If LEM, did you leave it stock or have it lightened to the 5.5 lb range? Can a non-LEM model be converted to LEM (and vice versa) by an HK armorer?
