The KCI USA KCI-MZ049 magazine delivers reliable feeding for 40 S&W firearms with its dual-capacity design accommodating both 10 and 15-round configurations. This aftermarket magazine combines hardened steel construction with polymer components for enhanced durability and consistent performance across extended shooting sessions.
What Makes This Different
Unlike standard factory magazines, the KCI-MZ049 features hardened steel internal components that resist wear from high-volume shooting while maintaining precise tolerances. The steel-reinforced feed lips prevent deformation under spring pressure, ensuring consistent cartridge presentation. This hybrid construction approach provides the corrosion resistance of polymer with the structural integrity of steel where it matters most.Key Features
