Springfield Armory Echelon 4.0FC 9mm Luger Pistol 4" Barrel 18+1 Round Black Aimpoint COA

Engineered to merge full-size capacity with a compact slide assembly, the Springfield Echelon 4.0FC pairs a 4-inch barrel with a full-length grip. With a host of patent pending features, this modular pistol is designed around a robust stainless steel chassis housed in a full-size frame with compact dust cover, offering a 17-round flush capacity and 20 rounds with the extended magazine. Factory equipped with the Aimpoint(R) A-CUT paired with the COA closed-emitter red dot sight, this integrated system mounts the optic directly to the slide without intermediary plates, reducing tolerance stacking while delivering a lower, more secure interface for enhanced durability and consistent zero retention.
