The Springfield Armory Echelon 4.5F 15-Round OD Green scales the full-size engineering and duty-ready performance of the Echelon platform into a 100% compliant configuration for states with a strict 15-round magazine capacity limit. Chambered in 9mm Luger, this full-sized handgun features a 4.5-inch cold hammer-forged steel barrel and a rugged Olive Drab Green Cerakote finish across its slide. Built entirely around the modular, serialized Central Operating Group (COG) chassis system, the internal fire control unit can easily drop into completely different grip sizes. Its revolutionary plate-free Variable Interface System (VIS) allows over 30 popular micro optics to mount directly and deeply into the slide configuration for an incredibly low profile. Designed to meet local capacity restrictions without losing duty-sized ergonomics, this model includes two flush-fitting 15-round magazines.
