The PMAG 21 GL9 is a sturdy, all-polymer magazine designed for 9mm GLOCK handguns. It holds up to 21 rounds, making it an excellent choice for competitions or tactical situations where extra capacity is required. The PMAG is built to last, with a durable polymer construction that is both lightweight and stiff. The stainless steel spring is corrosion-resistant, ensuring that the magazine will function reliably over thousands of rounds.

One of the key features of the PMAG 21 GL9 is its compatibility with a wide range of GLOCK models. It works with full-size, compact, and sub-compact double-stack GLOCK 9mm variants, with some protrusion below the grip. This makes it highly versatile and a great option for anyone who owns multiple GLOCK handguns.

The PMAG 21 GL9 offers several other benefits as well. The controlled-tilt follower is highly visible, allowing shooters to easily monitor the rounds remaining in the magazine. The floorplate is also designed for efficient operation, with a flared, easily removable design. And the paint pen dot matrix allows users to easily identify different loads in high-pressure situations.
