I was at the local fun shop today and found a J frame Smith, it was nickel plated, heavy (stainless or steel), shrouded hammer, rubber grips, app 1 7/8" barrel,pre-lock, non pinned/recessed. I looks like a 638 or 649 but the heavy gun with the nickel finish doesnt jive with my S&W history book. They wanted enough for it I wanted to do a little research but cant find such a critter.I am 99% sure it was a 6?? with no dash. Thanks for the help.
