Springfield Armory Echelon 4.5F Handgun 9mm Luger 17rd (1) & 20rd (1) Magazines 4.5" Barrel Black w/COA

Engineered with superior ergonomics and built to withstand the harshest conditions the Echelon 4.5F sets a standard for modern striker-fired duty pistols. With a host of patent pending features this modular pistol is designed around a robust stainless steel chassis housed in a full-size frame offering a 17-round flush capacity and 20 rounds with the extended magazine. Factory equipped with the Aimpoint 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.
