Design

edit

The .356 TSW is similar in size to a 9×19mm Parabellum or a 9×21mm (21.59 mm exactly) albeit with a much stronger case allowing for higher pressure and as much as 40% more energy at the muzzle. It was designed to be used in IPSC shooting events, but rule modifications specifically addressing its advantages were hurriedly established to make it irrelevant for competition. Due to renewed interest as a superior cartridge to 357 SIG, new production ammunition and caliber conversion kits for Glock 17 (Gen 1-4) and 19 (Gen 1-5) pistols became available in 2020.[2][3][4]
