Lynch, sorry I could not get back to you sooner. I finally got a hold of my UPS (United Pistol Supply) driver, Dave H. Dave relayed this info on this gentleman. The man operates under, Annis Arms (Dale Annis) Ellendale,DE 302-853-0584 and he is qualified as a S&W revolver smith. Email/ annisarms@comcast.net. I myself will keep this info because I live between Ellendale and Milford. I own several S&W revolvers that could need some attention in the future. If had a Taurus I would rather use someone else than use Taurus Service. There has been much too much bad talk about their customer service. I hope you get your weapon taken care of. Merry Christmas to you and your family.
