KCI USA KCI-MZ028 50rd Drum Magazine .40 S&W Glock Compatible

The KCI USA KCI-MZ028 drum magazine transforms Glock .40 S&W pistols into high-capacity platforms with 50 rounds of reliable feeding. This aftermarket magazine provides extended shooting sessions without frequent reloads, making it valuable for competitive shooting and extended range training.

What Makes This Different

Unlike standard 15-round Glock magazines, this drum configuration holds over three times the ammunition capacity in a compact cylindrical design. The hardened steel internal components resist wear from repeated cycling, while the polymer exterior reduces overall weight compared to all-metal alternatives. The spring-loaded feeding mechanism maintains consistent pressure across all 50 rounds, addressing common reliability issues found in cheaper drum magazines.

Key Features

• 50-round capacity increases shooting time between reloads by 230% over standard magazines
• Hardened steel internals and polymer construction balance durability with weight management
• Compatible with Glock models 22, 23, 24, 27, and 35 in .40 S&W caliber
• Spring-loaded feeding system maintains ammunition pressure throughout entire capacity
• Black finish matches standard Glock aesthetics and resists surface wear
• Drop-free design allows rapid magazine changes during competition or training
• Reinforced feed lips prevent deformation under repeated loading stress

Range testing shows consistent feeding across various .40 S&W ammunition weights and manufacturers. The drum's low profile maintains reasonable concealability compared to stick magazines of equivalent capacity. Competition shooters benefit from reduced reload frequency during rapid-fire stages, while training scenarios allow extended practice sessions. The polymer construction resists impact damage better than all-steel alternatives while maintaining the structural integrity needed for reliable function.
