If you live in a restricted-capacity state, the Springfield Armory 10-round Echelon 9mm magazine is purpose-built to keep you compliant while maximizing what the law allows. Designed specifically for the Echelon 4.0 Compact, this flush-fit magazine holds a full 10 rounds of 9mm and stays discreet in your carry gun—no external protrusion, no compromise on ergonomics. Whether you're in California, New York, Colorado, or another locale with capacity limits, this magazine gives you the most ammunition legally possible without sacrificing function or reliability.

Springfield engineered this magazine from stainless steel and applied a durable blacked-out coating that resists scratches and wear through daily use and regular training cycles. Numbered witness holes let you count rounds at a glance, so you know exactly what you're carrying without dropping the mag. The flush-fit design means it sits flush with the grip of your Echelon 4.0 Compact, maintaining the gun's natural handling and holster compatibility.

This is the magazine for shooters in restricted states who refuse to accept less. It's reliable, durable, and built to the same standard as Springfield's full-capacity options—just optimized for the legal reality where you live.
