The Springfield Armory Echelon 4.5F California Compliant Gear Pac sets a new standard for modern, striker-fired duty pistols while remaining perfectly tailored to meet the strict legal constraints of California's handgun roster. Built entirely around a revolutionary, self-contained, and serialized Central Operating Group (COG) chassis, this handgun delivers true uncompromised full-size recoil management, elite ergonomics, and rugged duty performance. This comprehensive factory package 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 EC9459BCA-PAC bundle 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 range execution.
