The Springfield Armory Echelon 4.5F pistol in 9mm with a factory Aimpoint COA red dot (brand part no. EC9459B-COA) is a modular, striker-fired duty pistol built around a robust stainless steel chassis. Springfield Armory mounts the closed-emitter Aimpoint A-CUT COA red dot directly to the slide without intermediary plates, reducing tolerance stacking for a more secure interface and consistent zero retention. The 4.5-inch hammer-forged steel barrel wears a Melonite finish, and the pistol ships with one 17-round flush magazine and one 20-round extended magazine. Black serrated front and rear sights back up the red dot for redundant aiming options. Among modular semi-auto handguns, this Echelon 4.5F configuration favors duty and competition shooters who want a factory-optic-equipped platform.
