Gentlemen, I have a 686 that I bought used in a pawn shop over twenty five years ago. It is a absolute honey and it has a home here forever. But, I was wondering. This 686 is a dash 0, Sn AAC 66XX and I understand that S&W did not have any short barrel 686's tell the dash 3 version. This has a square butt which makes it somewhat hard to carry. This 868 has the M mod so I know it has been back to S&W sometime in it's history. A letter is not worth it to me but I wish I knew how it left the mother ship. Was wondering if all the short barrel 868's were round butt guns.
