I have a sweet Ruger Stainless Security Six in .357 bought in 1976. I love it, but my wife can only shoot it SA, because of the DA trigger pull weight. She shoots the Glock great, but I think the Ruger has 3 times the trigger pull weight, but not sure. I have recommended a hand strengthening program but you can guess how that went. Has anyone had a trigger job? Any recommendations?
