The Springfield Armory Echelon 4.5F 15-Round Gear Pac sets a new standard for modern, striker-fired duty pistols while remaining perfectly optimized for capacity-restricted jurisdictions. Engineered around a revolutionary, self-contained, and serialized Central Operating Group (COG) chassis, this handgun delivers top-tier full-size control, elite ergonomics, and rugged duty performance. This comprehensive factory Gear Pac bundle arrives ready to deploy out of the box, featuring a slide-integrated Variable Interface System (VIS) hosting a pre-installed, co-witnessed Viridian® RFX11 green dot optic. The complete package comes protected in a heavy-duty, multi-compartment nylon zippered range bag alongside an expanded payload of four 15-round factory steel magazines to maximize your training strings.
