I'm not sure what you guys are talking about. I cut 2 coils off my spring, bent .5 so the end lays flat, then stretched the spring a tiny bit and reduced the pull from 8lbs down to 3lbs. I never added a set screw or shimmed anything. Just the spring cut mod. So I'm not sure why you guys are saying cutting the spring does nothing when clearly I've done it and know first hand it lightens trigger pull considerably.
