SKU: MGKCI-MZ04
The Mag Kci Usa For Glock 40 S&W 10rd magazine is a duty-grade backup and primary mag system engineered for law enforcement, security professionals, and armed civilians who depend on reliable ammunition storage. Built to Glock pattern specifications, this 10-round magazine serves as an essential component for agencies and individual operators running .40 S&W platform pistols. KCI USA magazines have become trusted alternatives in professional armed services worldwide, delivering consistent performance without the premium price tag of OEM components.
This magazine features a hardened steel insert fully encased in reinforced polymer construction, a proven design that protects the magazine body from impact deformation, corrosion, and operational wear. The steel feed lips maintain precise dimensional tolerances critical for reliable chambering under stress, while the polymer exterior absorbs shock without compromising structural integrity—essential for duty weapons that experience regular holstering cycles and equipment movement. The 10-round capacity strikes the tactical balance between magazine thickness and firepower, enabling faster magazine exchanges compared to extended variants while maintaining low-profile carry characteristics.
Operators running Glock 22, 23, 24, 27, and 35 platforms will find this magazine drop-in compatible with their existing holster and mag carrier setups. Tactical teams benefit from stocking multiple KCI USA magazines for training rotations and duty redundancy, while individual shooters value them as cost-effective backup capacity for competition or self-defense applications. Recommended for anyone standardizing on .40 S&W duty loads or building reliable magazine loadouts for critical applications.
