Dead Air DA402 P-Series Piston M13.5x1 LH Black

The Dead Air DA402 is a P-Series replacement piston designed to work as part of the P-Series booster assembly and spring on compatible Dead Air pistol-caliber suppressors. The piston threads into the booster and lets the user swap a host firearm's barrel thread pattern on a single suppressor platform.

This specific piston is cut to an M13.5x1 LH thread pattern - a left-hand, metric pitch - and is intended for use on 9mm tilting-barrel handguns. It installs into the suppressor booster in place of the factory piston. The piston is finished in a low-reflectance black that matches Dead Air's suppressor finish line, so it blends in cleanly at the muzzle end of the can.

The DA402 is compatible with the Ghost-M, Wolf-9SD, and Wolfman suppressors when used with the corresponding P-Series booster. It is not compatible with the Dead Air Odessa-9. The P-Series piston interface allows the suppressor to cycle properly on a semi-auto host by moving slightly with each shot, which is what makes this a tilting-barrel-ready part rather than a fixed direct-thread mount.

Whether you need a factory-spec replacement piston or want to adapt your Ghost-M or Wolfman to a host wearing an M13.5x1 LH barrel, the DA402 is a straightforward, purpose-built solution from Dead Air.
