A Wilson Combat checkered mainspring housing is a great way to improve the grip and appearance of your 1911 handgun. Our mainspring housings are fully machined from bar stock with real cut checkering. These high quality housings are a drop-in upgrade for handguns with cast or polymer housings and the same parts used in our custom guns.
Exclusive Wilson Combat round butt design for enhanced concealment and improved grip feel without reducing the hammer spring or drilling a new mainspring housing pin hole. The round butt mainspring housing requires frame reshaping/refinishing after installation.
