Banish Piston Features The Banish Piston is constructed from heat treated steel giving it the strength to handle the repeated thread engagement and recoil forces that come with moving a modular suppressor between different host firearms. This particular piston is cut to a 1/2x28 thread pitch for .45 Caliber applications matching one of the most common factory pistol barrel threads on the market today. Because the Banish 45 suppressor is designed around a quickly swappable piston system this part lets the same suppressor can body move seamlessly between multiple handguns without needing a separate suppressor for each host. The piston threads into the rear of the suppressor in place of the factory installed unit. Each piston is engraved with its thread diameter pitch and rotation direction which helps shooters correctly identify and install the right piston without guesswork since some Banish pistons use left hand threads. This clear labeling reduces the risk of cross threading or installing the wrong piston on a given host firearm. Because Banish manufactures a range of pistons to match many popular factory threaded pistol barrels owners of the Banish 45 suppressor have significant flexibility in building out a multi caliber multi host suppressor system.
