The Springfield Armory Echelon 4.0C Compact Comp Gear Pac integrates flat-shooting, recoil-reducing engineering into a carry-friendly platform built for everyday defense. Chambered in 9mm, this 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 strings of fire. Operating on a serialized Central Operating Group (COG) chassis inside a compact polymer frame, it provides exceptional ergonomics and cross-platform modularity. This inclusive factory Gear Pac bundle maximizes your 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 is neatly housed inside a premium, heavy-duty nylon zippered range bag paired with four factory steel magazines (one 15-round flush profile for low-profile carrying and three extended 18-round variants).
