The Springfield Armory Echelon 4.5F Comp Gear Pac is a full-size striker-fired 9mm pistol designed for duty, defense, and range performance. Built around Springfield’s serialized Central Operating Group chassis, the Echelon offers modularity, durability, and modern ergonomics.

This compensated model features an integral single-port compensator built into the slide and hammer-forged barrel, helping reduce muzzle rise and allowing faster follow-up shots. The slide is optics-ready with Springfield’s Variable Interface System, allowing direct mounting of many popular red-dot optics without adapter plates.

The Gear Pac configuration comes factory equipped with a Viridian RFX11 green dot optic, four magazines, and a Springfield range bag, giving shooters a complete range-ready package right out of the box.

Fully ambidextrous controls, interchangeable backstraps, and Springfield’s U-Dot sight system make the Echelon adaptable to a wide range of shooters and applications.
