The EOS originated as a steel frame variant of the popular Ares 4.25 and was engineered for the operator less concerned about weight than longevity. The steel frame adds roughly six ounces which, combined with porting, earns it the Perfect Zero designation. Chambered in 9mm with a 4.25 inch ported bull barrel, DLC finish, a match-grade trigger averaging 3 lb, and an optics-ready slide with interchangeable mounting plates. Weight 34.78 oz without magazine. Ships with three magazines (15, 15 and 17 rounds).
