Haven't measured what trigger pull weight is obtained with this striker spring, but the pull weight feels less than original. I also did some light polishing of sear and disconnector surfaces at the same time as I put in this spring. The feel of trigger is better together with the ascalon arms trigger shoe. Less creep and a more defined wall. A wall that I would like to be less hard and sharp, but for being a striker fire pistol that is half cocked until you start pulling the trigger, it's pretty damn good now. No light primer strikes with S&B factory ammo at least from my tests so far.
