I've sold three S&W's over the years. My first and second purchases, same day, transferred 10-6 heavy barrel to my mother in 1974, got it back after her passing in 1998.
My 15- Combat Masterpiece, sold it in '76 (and a motorcycle I had since '68 and a car I had since '70) at the behest of an ex-fiancée. Could not get any of those back, car was impounded and probably scrapped, motorcycle, I traced it (1982) but never got a reply to the letter I mailed. Combat Masterpiece, who knows where? I have replaced all three with kinda similar items, found a CM about a year and a half ago at work one day.
M&P, Fourth Change 1905,my third S&W. Traded it to a friend towards a Harley with the agreement that I had first dibs if he sold it. He passed away late 1996. His widow gave it to me for helping her with selling off his two collector cars and tools though it was a lousy way to reacquire it.
Haven't sold any others off since.
