Geez...all you auto guys should form a clubhouse or something...My J-Frame got polished hammer and sear surfaces, polished internal frame surfaces, new wolff mainspring (stock power but nicer feel) and reduced power rebound spring. I put a thousand or so (no kidding) rounds through it before I started to carry it after those changes without any issues. I carry that gun every day and I trust my life with it. It is a great point-shooting gun.
