Description

The Magpul PMAG GL9 delivers enhanced reliability and durability for Glock pistols chambered in 9mm Luger. This 21-round polymer magazine addresses common feeding issues while providing increased capacity over standard factory magazines.

What Makes This Different

Unlike traditional steel-lined magazines, the PMAG GL9 features Magpul's proprietary polymer construction with integrated steel feed lips. The magazine body resists cracking under extreme temperatures from -50°F to 180°F. Four-way anti-tilt follower technology eliminates double-feeds and bolt-over-base malfunctions that plague standard magazines.

Key Features

21-round capacity increases firepower over standard 15-17 round magazines
Compatible with Glock 17, 19, 19X, 26, 34, 45, and other 9mm double-stack models
Reinforced polymer body with stainless steel spring rated for 10,000+ compression cycles
Anti-tilt follower prevents feeding malfunctions and reduces bolt wear
Removable floorplate with paint pen dot matrix for identification
Textured grip panels provide secure handling during reloads
