The Dead Air DA401 is the 1/2x28 booster piston for Dead Air's P-Series mount system. Screw it onto a 9mm pistol with a 1/2x28 threaded barrel, and the booster (Nielsen device) lets your Ghost 45, Wolfman or Primal cycle reliably on a tilting-barrel handgun.
Dead Air sells this as the "P-Series Piston." Some distributors list it as the "Ghost Piston." It's the same part, DA401.
Will it fit?
| Works with | Dead Air Ghost 45, Wolfman, and Primal (Primal needs its HUB to P-Series adapter) |
|---|---|
| Your barrel thread | 1/2x28 (most 9mm pistols: Glock, SIG, S&W M&P, CZ and more with a threaded barrel) |
| You also need | Dead Air P-Series Booster Assembly and spring (included with the Ghost 45) |
| Does NOT work with | Dead Air Odessa-9 (uses its own piston), other brands' suppressors, M13.5x1 LH barrels (use DA402), .578x28 barrels (use DA405) |
Running a fixed-barrel host like a PCC or .22? Use the Dead Air Fixed Barrel Spacer in place of the booster spring.
