FWIW, I have had a "Charter Arms, Shelton" sn77xxx for over a year now (bought new), carried for more hours than I can guess with about 1000 rounds through it and except for being a bit smoother now, still just as tight as when new with 2" offhand groups at 20 yards all day long. I know it will not stand up as my S&W 696 has, but no failures yet and it carries much better for CCW.
