The Springfield Armory Echelon 4.0C Low Capacity OD Green adapts elite tactical modularity into a carry-friendly compact size configured for compliance in capacity-restricted states. Chambered in 9mm Luger, this striker-fired pistol features a 4-inch cold hammer-forged steel barrel and a slide finished in a tactical Olive Drab Green Cerakote. It is engineered around the modular, serialized Central Operating Group (COG) chassis system and employs the plate-free Variable Interface System (VIS) for deep, direct optic integration. Crucially, while this "LC" (Low Capacity) model limits ammunition storage to two flush-fitting 10-round magazines, it retains the standard slide profile with a visual viewing port loaded chamber indicator and does not incorporate a physical magazine disconnect safety.
