The Sig Armorer SuperStrut Mainspring System includes: the SuperStrut, ground and polished 20lb Wolff Spring, and new style high impact plastic 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.
Not for use in DAK pistols.
