The Springfield Armory Echelon 4.0C Compact Low-Capacity Gear Pac offers a premier, duty-ready defensive platform tailored specifically for compliance in capacity-restricted jurisdictions. Built completely around a revolutionary serialized, self-contained Central Operating Group (COG) chassis, this handgun delivers the adaptability of the full-size line within a highly concealable, low-profile compact frame format. The factory-configured package arrives completely field-ready, boasting a slide-integrated Variable Interface System (VIS) that directly holds a co-witnessed Viridian® RFX11 green dot optic. The entire EC9409BLC-PAC bundle comes packaged in a heavy-duty, padded nylon zippered range bag and features an expanded payload of four 10-round factory steel magazines to optimize training cycles.
