The Springfield Armory Echelon 4.5F Low-Capacity Gear Pac sets a new standard for modern, striker-fired duty pistols while remaining perfectly tailored for capacity-restricted jurisdictions. Built entirely around a revolutionary, self-contained and serialized Central Operating Group (COG) chassis, this handgun optimizes full-size control, superior ergonomics, and rugged duty performance. This comprehensive factory package arrives ready to deploy out of the box, boasting a patent-pending Variable Interface System (VIS) hosting a pre-installed, co-witnessed Viridian® RFX11 green dot optic. This complete Echelon Low-Capacity Gear Pac comes protected in a heavy-duty, multi-compartment nylon zippered range bag alongside an expanded loadout of four 10-round factory steel magazines to optimize your training strings.
