Magpul PMAG 21 GL9 — 21-round magazine for Glock 19

Magpul PMAG 21 GL9 is a high-quality, lightweight, and reliable magazine designed specifically for Glock pistols and compatible carbines that use 9×19 mm caliber magazines. The design is rated for 21 rounds, with compatibility also including 9×21 mm caliber, making the model a versatile solution for those who need increased capacity without losing compactness.

This new-generation magazine features enhanced strength and durability. The body is made of impact-resistant polymer, ensuring resistance to mechanical damage and reducing the overall weight. The spring is made of stainless steel, guaranteeing long-term, corrosion-free operation. The follower does not flex under pressure, requires no additional lubrication, and the magazine can be disassembled for maintenance without tools, simplifying field care.

The magazine's exterior surface has ribbing that facilitates grip and quick magazine changes, even in cold weather or when wearing thick gloves. A special marking field is located on the bottom, allowing users to label the type of loaded ammunition and avoid confusion during training or competitions. The baseplate retains its protective properties but has been thinned to reduce the overall profile without sacrificing impact resistance.
