I gotta question. I cant seem to back out the engagement screw. I got the over travel and spring tension to come loose. My question is this, when I leave the over travel alone, the way it came, and I back out the spring tension a couple turns, my trigger is pretty light. Can this be a substitute for doing all the other things. Or do I really need to play with the engagement and over travel? Once again, I cant break the engagement screw loose, but I was just experimenting and when I turned the spring tension screw out a little, I noticed my trigger pull was reduced dramatically. Was wondering if this would be OK.
