KCI USA 1911 Magazine 8-Round .45 ACP Black Steel MZ039

The KCI USA MZ039 magazine delivers reliable feeding for 1911 pistols chambered in .45 ACP with an 8-round capacity. This aftermarket magazine provides shooters with additional firepower while maintaining the classic profile that fits standard 1911 holsters and magazine pouches.

What Makes This Different

Unlike standard 7-round magazines, the MZ039 extends capacity by one round without significantly altering the grip length or draw characteristics. The black steel construction offers corrosion resistance superior to standard blued finishes. Heat-treated components ensure consistent spring tension and follower movement through thousands of loading cycles.

Key Features

• Heat-treated internal components for reliable feeding
• Standard 1911 footprint fits existing holsters and pouches
• Compatible with Government, Commander, and Officer frame sizes

Field testing demonstrates consistent feeding with various .45 ACP loads including hollow points, full metal jacket, and match-grade ammunition. The magazine functions reliably in competitive shooting environments and defensive applications. The steel construction withstands repeated drops on concrete without feed lip damage or spring compression issues.
