Introducing the E9, the first full size frame in the Evolution series. Optimized for the 9mm caliber, the E9 inherits smaller, thinner, and lighter than the Executive Commander. The E9 retains 100% 1911 controls and handling characteristics, and makes use of standard 1911 magazines. Some parts were completely re-designed to take advantage of modern improvements such as the new external extractor, easy-to-change front sight, smaller ledge-style rear sight, bull barrel, and a flat wire recoil spring system. The re-engineered slide has been shortened to 4", thinned substantially for weight reduction, and includes a unique 7-top custom cut, with special front and rear serrations.
