The Springfield Echelon 4.0FC 9mm with Aimpoint COA (Springfield Armory part no. EC9409BFC-COA) pairs a full-size grip with a compact 4-inch slide and a red dot already installed. Factory-equipped with the Aimpoint A-CUT and the COA closed-emitter red dot, the system mounts the optic directly to the slide without intermediary plates, which reduces tolerance stacking and helps hold zero. A stainless steel chassis lives inside the black polymer frame, and the serialized Central Operating Group is self-contained. It suits everyday carry and home defense for shooters who want an optic from day one.
