The Springfield Echelon 4.5F COA is a full-size striker-fired 9mm pistol engineered for duty performance, home defense, and high-volume range use. Built around Springfield’s innovative Central Operating Group (COG) chassis system, the Echelon offers true modularity, allowing grip modules to be swapped while maintaining a serialized internal core. Its 4.5-inch barrel delivers excellent balance, recoil control, and accuracy, all housed in a durable Black Melonite finished slide.
Outfitted from the factory with a precision red dot optic from :contentReference[oaicite:1]{index=1} and Springfield’s VIS direct-mount optic system, the Echelon eliminates the need for mounting plates while ensuring a low, secure optic fit. Enhanced grip texturing, luminous iron sights, and high-capacity magazines make this pistol a modern fighting handgun designed for speed, reliability, and adaptability in any environment.
