My 65-2 had a serrated trigger when I bought it. I don't particularly care for serrated triggers. So I made a search for polishing the trigger face on this forum, and lo and behold, there it was! So I very carefully took my Dremel tool and a tapered grinding stone to the trigger face, followed by a 120 grit sanding drum, and now I have a trigger that I like immensely. How simple is that?
Thanks to the fine folks on the S&W forum for the info!
