Product Information

These new polymer mainspring housings from STI are just the thing to help lighten up that carry gun. Functionally theses are the same as their steel constructed cousins, but at a substantial weight savings. If your carry gun is lighter and more comfortable to carry, you tend to carry it more often...and isn't that why you have it in the first place?

Designed to be a drop in fit, this mainspring housing my take a bit of fitting based on the variations between manufacturer's tolerances, etc.

This model fits 1911/2011 Government model pistols.
