The Springfield Armory Echelon 4.0C COA 9mm Pistol is purpose-built for concealed carry without compromising performance. Featuring a compact frame and 4-inch hammer-forged barrel, the Echelon 4.0C delivers the shootability and control of a full-size pistol in a more concealable package.

At the heart of the system is the innovative Central Operating Group (COG)—a self-contained, serialized chassis that enhances durability while allowing modular flexibility. This robust design ensures consistent performance while simplifying maintenance and customization.

This model is factory-equipped with the Aimpoint® A-CUT™, paired with the Aimpoint® COA® closed-emitter red dot sight. Unlike traditional optics mounting systems, the A-CUT allows the optic to mount directly to the slide without plates, reducing tolerance stacking and providing a lower, more secure interface. The result is improved durability, faster sight acquisition, and reliable zero retention in demanding conditions.

With a 15-round flush-fit magazine and an included 18-round extended magazine, the Echelon 4.0C offers excellent capacity for a compact platform. The ergonomic polymer frame, slim 1.2" grip width, and balanced weight make it ideal for everyday carry while maintaining excellent recoil control and handling.

Designed for modern defensive needs, the Echelon 4.0C COA delivers cutting-edge optics integration, modular design, and dependable performance—all in a carry-ready package.
