The Dead Air P-Series Piston .578×28 (Dead Air part no. DA405) is the piston that lets a P-Series suppressor run on a threaded pistol. Dead Air offers it in several thread pitches, and this one is made for .578×28 with a .45 bore. Dead Air lists the P-Series Piston for use with the Primal, Wolfman or Ghost 45, working as part of the P-Series Booster Assembly with its spring on tilting-barrel handguns. Because it moves with the booster, it is part of the setup rather than a fixed mount. It is the right pick for anyone matching a specific barrel thread on a tilting-barrel handgun.
