From the manufacturer
The Dead Air P-Series .45 Caliber Piston is engineered to mount compatible Dead Air suppressors (such as the Ghost-45, Wolfman, and Primal via P-Series adapter) onto large-bore pistol barrels featuring a .578x28 thread pitch. Featuring an enlarged interior through-bore sized specifically for .45 ACP projectiles, this piston operates within a booster assembly to temporarily decouple the mass of the suppressor from the barrel during firing, ensuring reliable semi-automatic cycling on Browning-style tilting-barrel handguns. Machined from high-strength steel and finished with a protective black coating, it maintains precise concentricity and strict tolerances under high-volume firing schedules. Compatibility: Dead Air Ghost-45, Wolfman, and Primal (using P-Series Booster Assembly)
