TJ’s Custom Gunworks 1911 Series ’80 to Series ’70 Conversion Shims© replace the gap used by the “Colt Series ’80 Firing Pin Block Actuating Levers” when removed by gunsmiths for crisper trigger pulls.
It is necessary to fill this frame gap so the sear will not wander over and lock up the sear / trigger mechanism. They fit in the frame cutout, permitting the Series ’70 slide and components to be fitted on to a Series ’80 frame. Drop-in fit, No alteration required.
Available in a factory standard .057″ width, as well as in .030″ and .060″.
