The Springfield Armory Echelon Pro 4.0FC Comp introduces a high-performance "Full Compact" hybrid layout to the modular Echelon striker-fired family. Built around the serialized Central Operating Group chassis, this 9mm handgun pairs a compact 4-inch slide assembly with a full-size frame to provide maximum shooting control and duty-ready capacity. Its billet-machined slide comes finished in durable Springfield Grey Cerakote and features an integrated muzzle compensator that works alongside a ported hammer-forged barrel to significantly reduce recoil. The black LightForged polymer grip is enhanced with a laser-sculpted, aggressive Badlands texture and includes a removable machined-steel flared magwell for seamless, high-speed reloads. Shipping with three 20-round extended steel magazines, this optics-ready handgun utilizes the Variable Interface System to enable low-profile, direct-mount attachment for over 30 red-dot sights.
