The Springfield Armory Echelon 4.5F Low Capacity Desert FDE adapts elite full-sized tactical engineering into a highly durable layout configured for compliance in capacity-restricted states. Chambered in 9mm Luger, this striker-fired pistol features a 4.5-inch cold hammer-forged steel barrel and a slide with a rugged Desert FDE Cerakote finish. It is built entirely around the innovative, modular, and 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 restricts 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.
