DuraMag SS 20rd 9mm Luger AR-15 Magazine - Black Stainless Steel (Model 2009041178CPD)

The DuraMag SS 20rd 9mm Luger AR-15 magazine is built to handle the real-world demands of 9mm carbines that chamber Colt-pattern mags. If you've fought with stubborn magazine loading or fed unreliable ammo through an AR-9, you know the frustration. DuraMag redesigned the geometry and spring behavior of these magazines to feed everything from target rounds to defensive hollow points and subsonic loads without drama. The 20-round capacity hits the sweet spot between firepower and portability for range days, training, or defensive scenarios.

What sets the DuraMag SS apart is attention to the details that matter in the field. The magazine body is made from 410 stainless steel, delivering corrosion resistance and durability without the weight penalty of heavier alloys. The advanced-geometry follower and EverFlex anti-fatigue spring work together to reduce binding and cycling issues that plague lesser 9mm AR magazines. Loading feels smooth from round one to round twenty—no white-knuckle fighting on the last few rounds.

Whether you're running a 9mm AR for home defense, competition, training, or casual shooting, having a reliable magazine is non-negotiable. The DuraMag SS 20rd strips away the compromise and gives you confidence in your ammunition feed, even with ammunition types other magazines choke on.
