I have a 3953 TSW that I bought used. If I remember right the empty shell that came with it was dated 9/?/2006. The Serial # is BDX1***. Would that mean it was made on that date???????????
It may very well have been made in 2006. Some 3rd gen. pistols are still being produced and the source I used (Smith & Wesson standard catalog 2nd edition) has a 2001 copyright.
