Springfield Echelon 4.0FC Frame w/Aimpoint COA - EC9409BFC-COA

The Springfield Armory Echelon 4.0FC is purpose-built for shooters who want full-size capacity without the bulk of a longer slide. By pairing a compact 4" barrel and slide assembly with a full-length grip frame, the 4.0FC delivers increased magazine capacity, enhanced control, and improved recoil management-all while maintaining faster handling characteristics than traditional duty pistols. At the core of the platform is Springfield's innovative Central Operating Group(TM) (COG), a serialized, self-contained chassis that allows true modular flexibility. Combined with the Variable Interface System(TM) (VIS) for direct-mount optic compatibility, this configuration-equipped from the factory with the Aimpoint COA-offers a hardened, professional-grade solution ready for duty, defense, or serious range work.The 4.0FC configuration combines a full-length grip for increased capacity and superior recoil control with a compact 4" slide for faster presentation and reduced overall length, striking an ideal balance between shootability and efficiency. A factory-mounted Aimpoint COA enclosed-emitter optic provides rugged, duty-ready reliability with a sealed design that protects against debris and moisture, while the Variable Interface System(TM) enables low-profile, direct-mount compatibility across leading optic footprints for enhanced durability under recoil. At its core, the serialized Central Operating Group(TM) delivers a modular, self-contained stainless steel chassis that allows grip module interchangeability without sacrificing rigidity. Fully ambidextrous controls ensure intuitive handling for all shooters, and tritium/luminescent U-Dot(TM) sights provide dependable backup aiming capability in low-light conditions.Specifications:Caliber: 9mmBarrel Length: 4"Configuration: Full-Size Grip / Compact Slide (4.0FC)Action: Striker-FiredOptic: Aimpoint COA (Factory Mounted)Optics System: Variable Interface System(TM)Frame: Polymer Grip Module with Serialized Central Operating Group(TM)Controls: Fully AmbidextrousFinish: BlackMagazines: 1-21rd Magazine and 1-17rd MagazineAccessory Rail: Integrated Picatinny Rail
