Precision 20 LPI Checkering for Positive Control

EGW applies 20 lines per inch (LPI) checkering across the mainspring housing to provide exceptional grip. Therefore, your hand remains stable during recoil, rapid fire, and reloads. In addition, the checkering improves traction without creating discomfort or bulk, allowing you to maintain confident, consistent control. Furthermore, it enhances both slow-fire accuracy and rapid follow-up shots.

Fully Machined Stainless Steel Construction

This mainspring housing is fully machined from solid stainless steel bar stock. As a result, it delivers superior strength, durability, and resistance to bending, cracking, or corrosion.
