Just bought new a new GP .357 4" SS. Trigger pull was very heavy, very rough. I did a "smoothing up" and polished all mating surfaces. Now the trigger pull is much smoother and has a nice crisp break, but is still very heavy. 8lbs+, my scale wouldn't measure that high. I expected something at least measurable. I have ordered a set of springs this morning. Hoping for 4-5 lbs SA. I have shot several older guns that had much lighter pull, I am surprised how heavy this one is, but it has been several years since I bought a new revolver, maybe they are just "worn in".
