All of my revolvers have light Wolff mainsprings and 12-13lb rebounds, whether I use them for range or carry. My guns with frame-mounted pins also wear Apex replacements. I load all my own ammo with Fed primers and have no ignition problems. The light springs, with a little lubrication, are as good as most action jobs. I can't imagine shooting stock S&W revolvers, except for some PC models. I also have a couple of better things to do than stay up nights, worrying about what the various lawyers might or might not say if, by some infinitesimal chance, I'm involved in a shooting.
