The Springfield Armory 9mm Echelon magazine in 18-round capacity gives you serious staying power between reloads. Built from stainless steel and finished with a corrosion-resistant black coating, this extended mag is engineered to last and handle the rigors of the range, competition, or duty use. The numbered witness holes let you count rounds at a glance—no guessing, no dropping the gun to check the mag. The extended polymer basepad gives your pinky a place to live on tactical reloads and makes the magazine substantially easier to strip from the gun when you need speed.

Engineered specifically for the Echelon 4.0 Compact platform, this magazine represents the kind of thought-out execution Springfield Armory is known for. The 18-round capacity bridges the gap between combat-ready capacity and still-concealable footprint—plenty of ammo for any realistic scenario without turning your EDC into a full-size target. The stainless steel construction resists wear and corrosion even if you run wet or spend time in harsh environments.

Whether you're upgrading from factory mags or building a reliable backup supply, this is the extension your Echelon deserves.
