Engineered with superior ergonomics and built to withstand the harshest conditions, the Echelon 4.5F sets a new 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.
