The Springfield Armory Echelon 4.5F Full Size Comp 15-Round Gear Pac pairs uncompromised full-size duty accuracy with recoil-flattening technology, custom-bundled for capacity-restricted jurisdictions. Chambered in 9mm, this defensive pistol features an integrally compensated slide and barrel system designed with a single, discrete top-facing port. This layout vents expanding high-pressure combustion gases upward to dramatically diminish muzzle rise and accelerate target re-acquisition during rapid fire strings. Operating on a serialized Central Operating Group (COG) chassis inside a rugged polymer frame, it provides exceptional ergonomics and customizable backstrap options. This comprehensive factory Gear Pac bundle maximizes range utility by shipping pre-outfitted with a direct-mounted Viridian® RFX11 green dot optic utilizing the pin-based Variable Interface System (VIS). The complete package comes protected inside a heavy-duty, multi-compartment nylon zippered range bag paired with four 15-round factory steel magazines.
