Springfield Armory Echelon 4.0C 9mm, 4" Barrel, Aimpoint COA

This Springfield Armory Echelon 4.0C delivers full-size performance in a package engineered for everyday carry. The 9mm semi-automatic features a 4-inch hammer-forged steel barrel with Melonite finish and a billet-machined slide ready for optics mounting. The compact polymer frame measures just 1.2 inches in grip width while maintaining impressive capacity with included 15-round flush and 18-round extended magazines. Fast target acquisition is enabled by tritium front sights paired with tactical U-Dot rear sights. The patent-pending Variable Interface System provides direct-mount compatibility with modern red dot optics, and this package includes an Aimpoint COA 3.5 MOA reflex sight featuring 50,000 hours of battery life and rugged 7075-T6 aluminum construction. At 24 ounces with the flush magazine and measuring 7.25 inches in length, the Echelon 4.0C combines concealability with the operating reliability expected from Springfield Armory's serialized Central Operating Group system.
