EGW Aluminum 1911 Mainspring Housing – 20 LPI – Black

Upgrade your 1911 with the EGW Black Aluminum Mainspring Housing and immediately improve grip, control, and overall handling. At the same time, this lightweight upgrade preserves the clean, classic look shooters expect from a traditional flat 1911 design. As a result, your pistol feels more responsive without sacrificing style or reliability.

Precision Aluminum Construction

Fully Machined from 6061 Aluminum

EGW machines this mainspring housing from solid 6061 aluminum, delivering strength while significantly reducing weight compared to steel housings. Consequently, your pistol balances better and feels quicker in hand. In addition, CNC machining ensures consistent dimensions, long-term durability, and a precise fit across compatible frames.

Black Finish for a Tactical Appearance

The black finish adds a clean, understated look that pairs perfectly with blued, blacked-out, or Cerakoted pistols. Therefore, this housing blends seamlessly into both duty and competition builds while maintaining a professional appearance.

Improved Grip and Shooter Control

20 LPI Checkering for Confident Handling

The 20 LPI checkering provides positive traction without being overly aggressive. As a result, you maintain solid control during recoil, rapid fire, and reloads. Furthermore, the checkering remains comfortable during extended range sessions, helping reduce fatigue while improving consistency.

Flat Housing for a Classic 1911 Feel

By using the traditional flat housing design, this mainspring housing preserves the original 1911 grip angle. Consequently, you benefit from predictable ergonomics, consistent hand placement, and smoother recoil management shot after shot.

Drop-In Fit and Broad Compatibility

Easy Installation with No Gunsmithing

EGW designs this housing as a true drop-in part. Therefore, installation is quick and straightforward, making it ideal for both new builds and simple upgrades. You can reuse your existing pins and springs or replace them as needed.
