TJ's 1911 Series '80 to '70 Conversion Shims are designed to fill the frame slot gap left after removing the Colt Series '80 firing pin block actuating levers.
The shims prevent the sear from wandering and locking up the trigger mechanism, ensuring a crisper trigger pull.
These shims are a no-alteration, drop-in fit, available in various widths including the standard .057”, as well as .030”, .060”, and .065”.
