What you can save is usually eaten up by the consignment fees. There will be variations based on percentage of retired people in population where you live, pistol magazine capacity regs,..... I would say $700 ot $800. Any reason you want S&W at inflated prices vs say Colt "Police Positive/Service" or Colt "Lawman"? Please keep in mind that new mid-sized .38/.357 revolvers are being manufactured by Colt.
