Keeping Traditions Alive Since 1953

This premium mainspring housing from Evolution Gun Works brings real substance to your 1911. Built from solid carbon steel bar stock and fully machined, it's a major step up from the polymer housings that come stock on most modern 1911s. The blued finish matches the retro Colt style look while providing corrosion protection.
The arched profile isn't just about looks. That curve naturally fills the web of your hand and distributes the rearward weight where you need it for better balance and tracking through recoil. You'll notice the difference right away compared to a flat housing, especially when running rapid pairs or working on accuracy. The serrated texture gives you solid traction even if your hands are wet or you're shooting in less-than-ideal conditions.
Because this is machined from bar stock rather than cast, you're getting a housing that will hold up to years of shooting. The construction method means tighter tolerances and no porosity issues you sometimes find in cast parts. It's the kind of upgrade that'll outlast your original housing by a wide margin.
The lanyard loop comes drilled and ready to go. Just install the supplied pin and you can attach a sling or lanyard for retention if you need it. Whether you run it or leave it empty, it's there without affecting the clean lines of the gun.
No, the housing itself comes ready to go. You'll need the pins and springs from your original mainspring housing to complete the installation, or you can purchase a complete replacement kit. The mainspring housing is the component itself, so the internal springs and pins are installed separately.
This will fit 1911 Government and Commander frame sizes from WWII and later production. It won't fit STI frames or short grip variations. If you have a standard full-size Government or Commander, you're good to go.
The arch fills your palm better and improves grip ergonomics, which helps with recoil tracking and balance. It also shifts weight rearward compared to flat housings. The serrations provide traction in wet conditions. If you've been running a flat polymer housing, the arched design feels noticeably more solid.
Yes, the housing comes pre-drilled for the lanyard loop with the pin included. You can attach a sling or lanyard for retention, or leave it empty if you prefer. It's a functional addition that doesn't compromise the classic 1911 look.
