Yeah, the Pythons were hand fitted to extremely tolerances-the best of ANY production revolver. Nowadays the S&W performance center equates the precision of those Pythons but none are smoother than those Pythons out of box. I've tuned/slicked up many revolvers and most designs CAN be tuned to the same degree. For absolutely the lightest smoothest revolvers I've done, the Ruger Security Six and Redhawk lockwork design lends itself to great double action trigger pull. Naturally most people don't go to the trouble to tune their revolvers to this degree so we'll stick with out of box stock revolvers. You're not going to go wrong with any quality made modern revolver IF IT FITS.
