Echelon Coa 9mm 4.50in 20 + 1 Black Semi Auto Pistol - Red Dot Optic

The Springfield Armory Echelon COA is a striker-fired 9mm pistol configured with a 4.5-inch barrel, a 20+1 capacity, and a factory-installed Aimpoint COA red dot optic. Its serialized chassis system supports a modular frame design, while the textured polymer grip provides a secure hold during practice, carry, and defensive use. An integrated trigger safety, optics-ready construction, and compact dimensions provide a practical balance of handling and performance.
