Springfield Armory Echelon 4.0FC Aimpoint COA 9mm 4-Inch Pistol, 17/20-Round

springfield armory echelon Details

The Springfield Armory Echelon 4.0FC Aimpoint COA 9mm 4-Inch Pistol, 17/20-Round uses the hybrid 4.0FC layout, pairing a 4-inch slide and barrel with a full-size grip module for control and capacity without the full 4.5-inch slide length. The Aimpoint COA configuration adds a factory-mounted closed-emitter red dot and A-CUT slide interface.

At the center of the platform is Springfield Armory’s serialized Central Operating Group, a stainless chassis designed to support the Echelon’s modular grip system. The Variable Interface System allows direct mounting of many popular optics without a traditional adapter plate, while ambidextrous controls, Adaptive Grip Texture, and a hammer-forged barrel support serious defensive and range use.
