The Mec-Gar MGG191800A delivers extended capacity for Glock 19 pistols with proven reliability trusted by military and law enforcement worldwide. This 18-round magazine combines steel construction with polymer components for optimal durability and feeding performance.

What Makes This Different

Mec-Gar manufactures magazines for major firearm companies as an OEM supplier, bringing the same quality standards to aftermarket products. The MGG191800A features heat-treated steel construction with anti-friction coating, compared to standard polymer magazines that may crack under stress. Independent testing shows Mec-Gar magazines maintain spring tension after 10,000+ compression cycles.

Key Features

• 18+1 capacity increases standard Glock 19 capacity by 3 rounds
• Heat-treated carbon steel body with anti-friction coating
• High-impact polymer baseplate and follower
• Chrome-silicon spring maintains consistent tension
• Drop-free design ensures reliable ejection

Range testing demonstrates consistent feeding across various 9mm ammunition types, from 115-grain FMJ to 147-grain hollow points. The extended capacity proves valuable for competitive shooting stages requiring higher round counts, while maintaining the compact profile essential for concealed carry applications. The steel construction resists deformation when dropped on concrete surfaces.
