The Springfield Armory Echelon 4.0C Compact Comp CA Compliant brings cutting-edge tactical innovation to California handgun owners within a completely roster-approved design. Sized down to a highly concealable 4-inch footprint, this 9mm platform incorporates an integrally compensated slide and barrel system featuring a single top-facing port that channels expanding gases upward to drastically mitigate muzzle rise for faster target tracking. To satisfy strict state requirements, it includes a factory magazine disconnect safety mechanism alongside a tactile loaded chamber indicator. Operating on the modular, serialized Central Operating Group (COG) chassis, this California Echelon Comp configuration features high-visibility tritium U-Dot iron sights and utilizes the patent-pending Variable Interface System (VIS) for unmatched direct-mount red-dot compatibility without adapter plates. It ships ready for civilian or defensive deployment with two 10-round factory steel magazines.
