356 TSW

The 356 TSW was an interesting cartridge that lasted only very briefly and is now out of print. It stands for 356 Team Smith & Wesson and was offered in several S&W autos as well as a few Centennial revolvers.


The S&W engineers created the little 9 mm round for the early 1990s IPSC venues. Their goal was to use existing pistol platforms to build competitive autos.


Loaded to the same overall length as the 9 mm Luger, the 356 TSW drove 147-grain JHPs fast enough to do the trick. Using a strong case about 21.5 mms in length, the 356 TSW made major with room to spare. At one point, I had several guns for evaluation and enjoyed shooting them very much. Basically, it was a way to hot rod the 9 mm round and it worked.


For one reason or another, the round was barred from competition and passed from the scene. S&W may still make some of the guns for sales in Europe, where things are different.

if someone had this ammo, where could he sell it and how much is the ammo worth. I tried looking it up on Smith & Wesson website but it didn't list it.

Chris -- I have a brand new 356 TSW. Seeking reloading info: did you mean you can make cases out of .223? Foolproof? Otherwise cut down the 9x23? Thanks.

The .356TSW is my dailey carry gun Because the friearm is 5" other than the factory comp holster I need a more concealable holster.thought about a Yaqui by Galco. Also I had a 9mm barrel fitted to the frame plus it will chamber and fire std 9X21 with no alterations. Reload the 147grain speer 147 grain flat nose with accurate #7 to duplicate factory loading contact accurate for starting point usess small pistol primer not rifle primer and can be made from .223 cases. Possible to fit 9X23.Briley still makes titanium bushng but has low inventory, suggest ordering 2 extra each one size smaller for wear. Have over 8000 rounds throug friearm with no wear.Bushings direct from Briley
