Rost Martin RM1C 15-Round 9mm Magazine - Steel/Polymer

The Rost Martin RM10024 RM1C magazine delivers reliable 15-round capacity for 9mm pistols with a proven steel and polymer construction. This magazine combines the strength of steel components with lightweight polymer materials for optimal balance and durability.

What Makes This Different

The RM1C features a hybrid steel-polymer design that reduces weight while maintaining structural integrity under high-stress conditions. The steel feed lips provide consistent cartridge presentation, while the polymer body resists impact damage and environmental exposure. This construction approach offers 20% weight reduction compared to all-steel magazines while maintaining the same reliability standards.

Key Features

• 15-round capacity for extended shooting sessions
• Steel feed lips ensure consistent cartridge feeding
• Polymer body construction for reduced weight and corrosion resistance
• Black finish provides low-visibility profile
• Drop-free design for rapid magazine changes
• Witness holes for quick round count verification
• Compatible with standard 9mm Luger ammunition

Field testing demonstrates reliable function through 5,000+ round cycles with minimal spring compression. The magazine maintains consistent feeding geometry across temperature ranges from -20°F to 140°F. Competition shooters report smooth ejection and positive seating in magwells, while the textured grip panels provide secure handling during tactical reloads.
