Yankee Hill Machine Company Sidewinder Piston 9mm 1/2x28 – Suppressor Piston Accessory

The Yankee Hill Machine Company Sidewinder Piston is a precision-machined suppressor piston designed for use with compatible pistol suppressors chambered in 9mm. This piston allows for direct threading onto barrels with 1/2x28 TPI threading, providing a secure, reliable interface between your host firearm and suppressor. The Sidewinder Piston enables the use of a Nielsen device (booster assembly) on tilting-barrel semi-automatic pistols, ensuring proper cycling and reliable function when shooting suppressed.

Manufactured from hardened steel with a durable finish, this piston is built to withstand the heat and pressure of sustained suppressed fire. It's compatible with Yankee Hill Machine Sidewinder series suppressors and other systems that accept standard piston attachments. The 1/2x28 thread pitch is the industry standard for 9mm pistol barrels, making this piston a direct-fit solution for most 9mm handguns.
