Built for duty, defense, and uncompromising performance, the Echelon™ 4.5F from Springfield Armory redefines what a modern striker-fired pistol should be. Designed with enhanced ergonomics and engineered to endure the harshest operational environments, the 4.5F delivers full-size capability with cutting-edge modularity.

At the core of the system is the Central Operating Group (COG)—a robust, serialized stainless steel chassis that houses the pistol’s operating system. This innovative design provides unmatched strength, consistency, and adaptability across configurations while maintaining reliability under extreme conditions.

The Echelon 4.5F is factory-equipped with the advanced Aimpoint® A-CUT™ interface, seamlessly integrating the included Aimpoint COA® closed-emitter red dot sight. This direct-mount system eliminates the need for adapter plates, reducing tolerance stacking and placing the optic lower in the slide for faster target acquisition, enhanced durability, and superior zero retention.

With a 4.5-inch hammer-forged barrel, full-size frame, and included 17-round flush-fit and 20-round extended magazines, the Echelon 4.5F is purpose-built for professional use. Whether on duty, at the range, or for home defense, this pistol delivers the accuracy, capacity, and rugged performance serious shooters demand.
