The Springfield Armory Echelon 4.5F Full Size Comp CA Compliant Gear Pac delivers uncompromised full-size duty accuracy and flat-shooting recoil performance in a 100% roster-approved setup. Chambered in 9mm, this defensive pistol features an integrally compensated slide and barrel system designed with a single, discrete top-facing port. This configuration vents high-pressure combustion gases upward to dramatically diminish muzzle rise and accelerate target re-acquisition during rapid strings of fire. Fully tailored to pass strict state safety regulations, it incorporates a tactile loaded chamber indicator and an integrated magazine disconnect safety mechanism. Operating on a serialized Central Operating Group (COG) chassis inside a rugged full-size polymer frame, it provides exceptional ergonomics and ambidextrous handling. This comprehensive California Gear Pac bundle maximizes out-of-the-box readiness by shipping pre-outfitted with a direct-mounted Viridian® RFX11 green dot optic utilizing the pin-based Variable Interface System (VIS). The complete kit comes safely protected inside a heavy-duty, multi-compartment nylon zippered range bag paired with a robust layout of four 10-round factory steel magazines.
