Built by Springfield Armory, the Echelon 4.0FC Gear Pac model is a complete, ready-to-run defensive handgun system engineered for concealed carry, home defense, duty use, and range performance.

This modular design allows shooters to customize fit and ergonomics while maintaining consistent reliability and performance.

This system ensures a low-profile, secure optic mount designed for durability and repeatable performance under demanding conditions. The Echelon 4.0FC Gear Pac includes a 4-inch hammer-forged barrel that balances accuracy with concealability, while the full-size grip improves recoil control and supports higher capacity. Aggressive slide serrations and a corrosion-resistant Melonite finish enhance durability and handling in adverse environments.

Ergonomics are further improved with fully ambidextrous controls, aggressive grip texturing, and interchangeable backstraps for a customizable fit. Equipped with Contrast U-Dot sights provide fast and reliable target acquisition. The Echelon 4.0FC Gear Pac 9mm package includes four magazines, the Viridian RFX11 green dot optic, a magazine loader, interchangeable backstraps, and a premium carry case, delivering a complete ready-to-use pistol system. Combining modular engineering, advanced optics integration, high capacity, and duty-grade reliability, the Springfield Echelon 4.0FC Gear Pac 9mm stands out as a modern, feature-rich handgun built for concealed carry, defensive use, training, and real-world performance.
