KCI USA 31-Round .40 S&W Magazine for Glock 22/23/24/27/35

The KCI USA KCI-MZ012 extends your Glock's capacity to 31 rounds of .40 S&W ammunition, delivering substantial firepower for competitive shooting and tactical applications. This extended magazine transforms standard Glock pistols into high-capacity platforms without compromising reliability or function.

What Makes This Different

Unlike factory 15-round magazines, this extended design nearly doubles your ammunition capacity while maintaining the proven Glock magazine interface. The hardened steel construction reinforces critical stress points that typically fail in high-capacity aftermarket magazines. KCI USA incorporates a reinforced polymer body with steel internals, creating a magazine that feeds consistently through extended shooting sessions.

Key Features

• 31-round capacity increases firepower by over 100% compared to standard magazines
• Hardened steel feed lips and internal components resist deformation under pressure
• Drop-free design ensures reliable ejection during tactical reloads
• Compatible with Glock models 22, 23, 24, 27, and 35 in .40 S&W
• Polymer body construction reduces weight compared to all-steel alternatives
• Standard Glock magazine catch interface requires no modifications

Competitive shooters benefit from reduced reload frequency during stages requiring high round counts. The extended length provides additional grip surface for enhanced weapon control during rapid fire sequences. Law enforcement and security professionals gain tactical advantages in scenarios where ammunition capacity directly impacts mission success.
