Springfield Armory Echelon COA 9mm 4" Bbl Black Handgun w/ Aimpoint COA Optic, 2x10rd Mags EC9409BLC-COA

The Springfield Armory Echelon 4.0C Compact COA Low-Capacity integrates rugged, weather-sealed optical superiority with a carry-friendly platform engineered specifically for restricted-capacity jurisdictions. Built completely around Springfield's serialized, modular Central Operating Group (COG) chassis, this defensive 9mm scales down to a compact frame footprint to maximize concealment profile without forfeiting duty-grade durability. The defining hallmark of the EC9409BLC-COA configuration is the factory-integrated Aimpoint® A-CUT slide profile, hosting a pre-installed Aimpoint® COA closed-emitter red dot optic. This specialized direct-mount interface utilizes a deeply recessed wedge architecture that completely drops intermediate plate configurations—significantly dropping height-over-bore measurements while isolating the optic body from extreme shear strain. Shipped with two compliant 10-round steel magazines, this weather-sealed setup ensures seamless tactical readiness under the most punishing ambient conditions.
