Re: What model S&W is this?
This gun was built during the time S&W used pinned barrels and recessed chambers in the cylinder. It also has the thru hardened hammer and trigger. Most likely the action is as smooth as glass. Sometimes they get a little out of time, especially if they it had a real steady diet of magnums.
Keep it! These haven't been made in several years. They, at one time, would bring up to $750 with box and papers. With a sucky economy the numbers above are about right.
