I have a few s&w revolvers (686 plus, 60, etc) and I was wondering if there was any known reputable buisness that do trigger work (more smooth and preferable a trigger pull in double action around 9 pounds to 11?). Would it be better to do it to a new production s&w over one of my older ones or does it not matter? Mainly considering it on a snub j frame or considering buying one that already has work done or new for the purpose of concealed carry. I never had a issue with the triggers but a few of my friends dispised the trigger on them and after having a rifle with trigger work that made it so much easier to hit accurate, I wanted to do that to a backup carry J frame. I'm mainly looking for what would it cost roughly as I've only found 2 sites that seem to offer it and a load of horror stories of people not replacing the spring but clipping them or something along those lines. Thanks.
