.356 TSW
The .356 TSW (.356 Team Smith & Wesson) is a centerfire handgun cartridge that was designed by Smith & Wesson in 1994, and released commercially in 1995. The .356 TSW is very similar in size to a 9mm Luger, or a 9x21mm. It was designed to be used in IPSC shooting events, but rule changes addressing the use of the new cartridge made it obsolete almost immediately. As a result, it's mostly an obscurity, though ammo appears to still made (as of early 2021) by CorBon and Underwood.
