KCI USA MZ047 CZ 75 Magazine 9mm 17rd Steel/Polymer Black

The KCI USA MZ047 magazine delivers reliable feeding and extended capacity for CZ 75 series pistols. This aftermarket magazine combines hardened steel construction with polymer components to provide shooters with a cost-effective alternative to factory magazines without compromising performance.

What Makes This Different

Unlike standard factory magazines, the MZ047 features a dual-material construction that balances durability with weight reduction. The hardened steel body provides structural integrity under repeated loading cycles, while polymer components reduce overall weight by approximately 15% compared to all-steel alternatives. The 17-round capacity extends shooting sessions and provides tactical advantages over standard 10-round configurations.

Key Features

• 17-round capacity for extended shooting without frequent reloads
• Hardened steel body construction for long-term durability
• Polymer follower and baseplate reduce weight and friction
• Compatible with CZ 75, CZ 75B, CZ 85, and similar frame pistols
• Anti-tilt follower design prevents feeding malfunctions
• Heat-treated steel spring maintains consistent tension
• Matte black finish resists corrosion and wear

Field testing demonstrates consistent feeding across various 9mm ammunition weights from 115 to 147 grains. The magazine functions reliably in competitive shooting environments, law enforcement training scenarios, and recreational range sessions. The steel construction withstands repeated drops on concrete surfaces while maintaining dimensional stability. Temperature cycling from -20°F to 140°F shows no impact on spring tension or feeding reliability.
