This Mainspring Housing from Ed Brown (brand part no. 816-ARCH) is finished in blue and sized for the Commander-frame 1911, built with an arched profile and serrated texture rather than a flat, checkered one. The arched profile changes the way the grip fills the hand compared to a flat housing, and some shooters prefer it for how it points the pistol.
