The SilencerCo Piston 1/2"x28 XL is a precision-engineered component designed specifically for cycling semi-automatic pistol actions when paired with compatible threaded barrels. This piston is essential for operators, competitive shooters, and trained civilians who suppress pistol caliber firearms and require reliable cycling during semi-automatic fire.
Manufactured from durable 17-4 stainless steel and heat-treated for maximum longevity, this piston enables reliable cycling in semi-automatic configurations. The 1/2"x28 thread pattern is the industry standard for most 9mm and .45 ACP centerfire pistols, ensuring compatibility with a wide range of firearms. For fixed-barrel applications, a separate fixed barrel spacer (sold separately) can be added for configurations where semi-automatic cycling is not required.
The robust construction resists corrosion from repeated firing, cleaning solvents, and environmental exposure, making it a practical choice for shooters who run multiple suppressors or host firearms. This piston is ideal for those looking to enhance their shooting experience with reliable performance and compatibility across various platforms.
