The Springfield Armory Echelon 4.5F Full Size Comp CA Compliant delivers next-generation duty performance to California shooters in a 100% roster-approved layout. Built on a full-size polymer frame with a 4.5-inch hammer-forged steel barrel, this 9mm platform features an integrally compensated slide and barrel system. The single top-facing port vents expanding combustion gases straight upward to neutralize muzzle climb and flatten recoil. Fully customized for state compliance, the pistol integrates a tactile loaded chamber indicator and a factory magazine disconnect safety mechanism. Centered around the serialized Central Operating Group (COG) internal chassis, it utilizes the innovative, pin-driven Variable Interface System (VIS) for a direct-to-slide micro red dot mount without extra plates. This rostered configuration comes standard with high-visibility tritium U-Dot iron sights and two 10-round factory steel magazines.
