Frequently Asked Questions

What does the mainspring housing do? It forms the bottom-rear of the grip frame and houses the mainspring that powers the hammer, while also shaping the grip’s backstrap.

Why choose a smooth housing over a checkered one? A smooth housing gives a cleaner, less abrasive backstrap feel than a checkered or arched housing, which comes down to shooter preference.

Does this fit the Officers or Commander frame? This listing is built for the Government frame; check with us before ordering if you have a different 1911 frame size.
