Dead Air P-Series Piston 9/16-24 Black DA403 Suppressor Piston

Description

One suppressor, multiple hosts. That's the whole point of the piston system Dead Air built into the P-Series lineup, and this 9/16-24 piston is the piece that gets your .40 caliber pistol into the rotation. It swaps into the P-Series booster assembly in seconds, so instead of buying another can, you're just buying the interface that matches your barrel threads.

Why the P-Series Piston Matters on a Tilting Barrel

Most semi-auto pistols use a tilting barrel design, and hanging a suppressor off the muzzle adds enough weight to interfere with cycling. The booster assembly and piston work together as a Nielsen device, letting the barrel do its thing under recoil so the gun runs reliably suppressed. The piston is also what keeps everything concentric, which means proper alignment between the bore and the baffle stack every time you thread it on. Machined from tough 4140 steel with a black finish, this one is built to shrug off the heat and pressure that come with regular suppressed range time.

Compatibility Across the Dead Air Lineup

This piston works with the P-Series booster assembly found in the Wolfman, Ghost 45, and Ghost-M, plus the Wolf-9SD and the Primal when it's wearing the P-Series adapter. The booster assembly itself is sold separately, so if your can shipped with a fixed mount, plan on picking one up. One heads up: this piston is not compatible with the Odessa-9, which uses its own piston design.

Getting the Right Fit

The 9/16-24 thread pattern is the common pitch for .40 S&W pistol barrels, so double check the threads stamped on your barrel or listed by your barrel maker before ordering. Match the threads, match the caliber, and you're set. Keep a piston on hand for each host in your safe and swapping the suppressor between guns becomes a thirty second job instead of a reason to leave one at home.
