Dead Air P-Series Piston M14.5x1LH
The Dead Air P-Series Piston M14.5x1LH is a replacement piston designed for users who run Dead Air's P-series booster assemblies on tilting-barrel handguns. If you already own a Primal Wolfman or Ghost 45 suppressor and want to expand your setup across multiple hosts, or simply need a spare, this piston gives you the flexibility to do it without buying a whole new suppressor. It threads on at M14.5x1 (left-hand) and works as part of the complete P-series booster system with its matching spring to cycle your suppressor on semi-automatic pistols.
Suppressors that use pistons rely on the recoil impulse of the gun to cycle a booster assembly, which helps with reliability and back-pressure management on suppressed guns. Having extra pistons on hand means you can set up the same suppressor on multiple pistols without swapping hardware every trip to the range or field. This piston is a straightforward parts-bin essential for anyone serious about running the same can across a few different hosts.
Dead Air's piston-driven suppressors are built with precision tolerances; if you're running a P-series can, keeping a spare piston around is smart insurance against wear or loss. Make sure your specific suppressor model is compatible with the P-series booster system before ordering—this piston is engineered for that platform and requires the corresponding spring and booster to function.

Frequently Asked Questions
What suppressors does the Dead Air P-Series Piston work with?
This piston is designed for Dead Air suppressors equipped with the P-series booster assembly, including the Primal Wolfman and Ghost 45. It will not work with other suppressor models or booster platforms.
Can I use this piston on any handgun?
The P-series piston is designed for tilting-barrel handguns. Compatibility with your specific pistol depends on whether your suppressor is set up with a P-series booster and the correct barrel threading. Check that your suppressor and host firearm are compatible with the P-series system before purchasing.
Do I need the spring to use this piston?
Yes. This piston works as part of a complete P-series booster assembly and requires the matching spring to function correctly. The piston and spring work together to cycle the suppressor on semi-automatic fire.
Why would I buy an extra piston?
Extra pistons let you set up the same suppressor on multiple pistols without swapping components every time. They're also useful as spares to have on hand in case of wear or loss over time.
