The .356 TSW (356 Team Smith & Wesson) is a centerfire pistol cartridge designed by Smith & Wesson in the mid-1990s.


The .356 TSW is similar in size to a 9x19mm Parabellum or a 9x21mm. It was designed to be used in IPSC shooting events, but rule modifications addressing its use quickly made it obsolete,[2] pushing the round into obscurity.
