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.

• Fully Machined from bar stock aluminum with real cut checkering
• Low luster, glass bead hard anodized finish
• Drop in fit for most full size 1911 handguns
• Minor fitting may be required in some 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.
