From the first grip, this precision-machined component improves control, strengthens durability, and elevates the overall fit and finish of your pistol. Because EGW machines this housing from solid stainless steel, it delivers long-term reliability for competition, duty use, and everyday carry alike.

Precision Checkering for Consistent Control

The 25 LPI checkering places traction exactly where your support hand needs it most. As a result, your grip stays locked in during rapid fire, aggressive reloads, and high-stress shooting. At the same time, the checkering remains comfortable for extended range sessions. Therefore, you gain stability and confidence without adding unnecessary bulk or discomfort.

Solid Stainless Steel Construction

Unlike plastic or cast housings, this EGW mainspring housing starts as solid stainless steel bar stock. Consequently, it resists flexing, cracking, and long-term wear. In addition, stainless steel naturally resists corrosion, making it ideal for hard use and varying environments. The glass-beaded finish further enhances durability while providing a clean, uniform appearance that complements custom and factory STI builds.

Simple Installation and Proven Compatibility

This mainspring housing installs easily using your existing pins and springs, or with readily available replacements. Because it follows STI-style dimensions, it serves as a direct upgrade or replacement for factory or worn housings. As a result, you spend less time fitting parts and more time shooting.
