DuraMag SS 9mm Colt Pattern AR Rifle Magazine Black 9mm Luger 10/rd

The DuraMag SS 9mm Colt Pattern AR Rifle Magazine Black 9mm Luger 10/rd is a precision-engineered magazine purpose-built for 9mm Luger ammunition in AR-platform rifles configured with Colt-pattern feed lips. Developed by C Products Defense Inc.—a manufacturer with deep roots in law enforcement and military supply—this magazine addresses the specific reliability demands of tactical operators, competition shooters, and civilian gun owners transitioning AR platforms to 9mm caliber. The 10-round capacity reflects practical compliance with magazine restrictions in several states while maintaining full operational capacity for training, home defense, and duty applications.

Built from stainless steel construction, the DuraMag SS resists corrosion and spring degradation that can plague standard steel magazines in harsh field environments—critical for operators storing loaded mags long-term or operating in coastal or high-humidity regions. The Colt pattern feed lips are precisely geometry-tuned to chamber 9mm rounds reliably without double-feeding or nosedives, a common failure point in magazines adapted for caliber conversion. The follower and spring stack are engineered to maintain consistent upward pressure across the full 10-round load cycle, ensuring smooth feeding whether firing suppressed, unsuppressed, or under rapid-fire strings. At 0.24 lbs unloaded, the magazine adds minimal weight to the platform while the compact 4.75 x 1 x 8-inch profile seats flush in standard AR magwells without modification.

This magazine is fully compatible with any AR-15 platform rifle (direct impingement or piston) that has been properly converted to 9mm Luger with a compatible barrel, bolt carrier, and magazine well—no gunsmithing required for installation. Law enforcement agencies using 9mm AR conversions for training and transition courses, competitive shooters running 3-gun or PCC divisions, and civilian owners building economical 9mm platforms benefit most from DuraMag's reliability pedigree. Purchasing multiple DuraMag SS magazines ensures consistent feeding characteristics across your magazine rotation and provides reliable backup capacity for extended range sessions or duty readiness.
