The Springfield Armory Echelon 4.0C 15-Round OD Green adapts the highly modular, duty-grade features of the Echelon platform into a carry-sized frame, specifically configured for states with a strict 15-round magazine capacity limit. Chambered in 9mm Luger, this striker-fired pistol utilizes a 4-inch cold hammer-forged steel barrel and features a durable Olive Drab Green Cerakote finish across its slide. At its core is the self-contained, serialized Central Operating Group (COG) chassis system, which allows the fire control unit to be easily swapped into different grip modules. Its innovative plate-free Variable Interface System (VIS) allows over 30 popular micro optics to mount directly and deeply into the slide configuration. Designed to meet local capacity restrictions, this model includes two flush-fitting 15-round magazines.
