Silencer Central® BANISH® 9 Replacement Booster Piston – 9mm – 1/2x28 TPI – Black Steel – 100000311173
The Silencer Central® BANISH® 9 Replacement Booster Piston (100000311173) is a 2026-spec precision-engineered NFA attachment component manufactured specifically to dictate the cycling timing and booster retention parameters of the modular BANISH 9 silencer matrix. While fixed barrel utility setups like pistol caliber carbines (PCCs), lever-action rifles, or bolt guns can comfortably host direct-thread suppressors, standard tilting-barrel semiautomatic handguns (such as Glocks, SIG Sauers, or Smith & Wessons) will immediately short-cycle, failure-to-feed, or jam due to the parasitic nose weight of the suppressor assembly. This replacement piston (810171225429) interfaces directly with the proprietary BANISH Micro Booster™ system, forming a highly tuned Nielsen device that acts as a kinetic energy uncoupler to preserve factory firearm reliability.
Precision-machined from ordnance-grade high-tensile carbon steel and treated with an ultra-hard, friction-reducing matte black oxide finish, this piston is engineered to shrug off severe operational gas temperatures, mechanical impacts, and aggressive cleaning chemicals. Cut to the universal American standard 1/2x28 TPI (Threads Per Inch) pitch, it transforms your multi-caliber modular silencer into a dedicated 9mm or sub-caliber handgun host. The outer structural shell features precise, parallel alignment guide lanes that slip flawlessly into the Micro Booster booster cage. This design completely eliminates the internal frame yaw or axial twisting that causes catastrophic, accuracy-destroying baffle clips or front-cap strikes. Complete with crisp, clean laser engraving detailing thread specs for instantaneous inventory identification during range bag swaps, this steel piston is a mandatory component for keeping your tactical handguns running suppressed on mute.
Includes: (1) Silencer Central BANISH 9 Suppressor Booster Piston (1/2x28 TPI / Black Steel Construction).
*Compatibility Note: This piston is explicitly designed and indexed to fit inside the Silencer Central BANISH 9 modular suppressor framework utilizing the internal Micro Booster assembly. It features standard 1/2x28 threads, perfectly mating to the vast majority of factory-threaded 9mm, .380 ACP, and rimfire handguns on the market.
Key Features
- Universal 1/2x28 Handgun Threading: Instantly translates the modular rear hub of your silencer to accept standard 9mm barrels, including Glock, SIG, and Smith & Wesson factory muzzles.
- Optimized for the Micro Booster™: Functions seamlessly inside the BANISH 9 booster cage assembly, introducing a floating spring relief path that enables the pistol barrel to tilt and cycle naturally.
- Heavy-Duty Hardened Steel Core: Monolithic steel engineering prevents premature thread deformation, high-temperature warping, or spline wearing over thousands of firing strings.
- Slick Matte Black Oxide Polish: Industrial protective layer dramatically reduces operational carbon scaling build-up, ensuring the piston cleans up quickly during routine teardowns.
- Precision-Ground Alignment Slats: Parallel indexing cuts maintain strict axial concentricity with the handgun bore line, preventing dangerous baffle strikes and maximizing group accuracy.
- Laser-Etched Specification Matrix: Deeply engraved with thread indicators so you can quickly identify your mounts inside multi-can gear cases.
