The EOS originated as a steel frame variant of the popular Ares 4.25, engineered for the operator less concerned about weight than longevity. The steel frame's additional weight combined with porting earns it the Perfect Zero designation. The v3 adds billet slides, redesigned optics plates with improved retention, interchangeable Glock-style front sights, improved grip ergonomics, a revised feed ramp angle and patent-pending angled grip bushings. Chambered in 9mm with a 4.25 inch ported bull barrel and DLC finish, and a match-grade trigger averaging 3 lb. Weight 34.78 oz without magazine. Ships with three magazines (15, 15 and 17 rounds).
