Built for modern defensive and duty applications, the Springfield Armory Echelon delivers a forward-thinking design centered around modularity, adaptability, and performance. Featuring a 4-inch barrel and paired with a factory-installed Viridian RFX11 Green Dot, this pistol is ready for immediate deployment-whether on the range, for home defense, or professional use. With four included magazines, it offers extended readiness straight out of the box. At the heart of the Echelon is Springfield's Central Operating Group(TM), a serialized chassis system that provides a robust, modular foundation for customization. This system allows shooters to adapt their setup while maintaining reliability and consistency across configurations. The Variable Interface System(TM) sets the Echelon apart, enabling direct mounting of a wide range of optics without the need for adapter plates. The included Viridian RFX11 Green Dot enhances target acquisition speed and visibility, particularly in bright conditions, making it a valuable addition for both defensive and range applications. Fully ambidextrous controls ensure intuitive operation for all shooters, while the ergonomic frame design promotes a secure, natural grip. Combined with a consistent trigger and a 4-inch barrel for balanced accuracy and handling, the Echelon is engineered to perform under pressure. With four magazines included, it's a complete, ready-to-run platform for serious users.
