Here is what I have done so far. Lighten recoil spring to reduce muzzle lift Lighten striker spring to help reduce trigger pull polished all contact points in trigger geom thinned, annealed, and bent OE connector to reduce slide friction Super light spring on safety pin Etc, a few other small things. I am wondering if adding the heavier spring on the trigger will help much in my efforts to reduce pull force? I am very happy in the direction I am headed and really feels like it will be very reliable where it is now. Anything I missed in the trigger job? If the spring is a good idea at this point, where can I get one on the cheap?
