Dead Air DA403 P-Series Piston 9/16x24 Black

The Dead Air DA403 is a P-Series piston designed for use with Dead Air's P-Series booster assembly. This piston threads directly onto a pistol barrel in the 9/16x24 thread pattern and drops into the booster of a compatible Dead Air suppressor, allowing tilting-barrel pistols to cycle reliably while suppressed. P-Series pistons are built to swap quickly between host firearms so a single suppressor can move between pistols of different calibers with minimal downtime.

The 9/16x24 thread pitch identifies this as the .40 S&W piston in the P-Series line. It is compatible with Dead Air's Ghost-M, Wolf-9SD, and Wolfman P-Series pistol suppressors, making it a direct replacement or spare for .40-cal hosts. Finished in black to match the standard Dead Air suppressor line, the DA403 keeps your P-Series suppressor set up and running on your favorite .40-cal pistol.
