Sig Sauer Silencer Piston 40 S&W 9/16x24

This silencer piston is made by Sig Sauer and is constructed out of heat-treated stainless steel. The addition of this piston allows the user to convert their .40 S&W or 10mm subsonic to a right handed 9/16x24 threat pitch. Installation is quick and easy, just replace the original piston with this conversion in your suppressor to match your barrel’s thread pattern.
