The Sig Armorer P220 SuperStrut Mainspring System includes the Superstrut, ground and polished 20lb Wolff Spring, and new style mainspring seat. Do NOT use Superstrut; or the factory E2 Strut for that matter, with an aluminum or any other metal mainspring seat. The seat is designed to be made from plastic as it works as a bearing against the strut. Metal seats WILL be gouged by the strut and over time will create enough friction to reduce mainspring force and make the double-action pull both gritty and heavy.
