Magpul was founded in 1999 with the intent of developing a simple device to aid in the manipulation of rifle magazines while reloading under stress. The company’s name comes from this original product called the Magpul. Over the last seventeen years Magpul has continued to grow and develop using much the same mission and process with a focus on innovation, simplicity, and efficiency.

The PMAG 21 GL9 is a 21 round 9mm after market Glock magazine that offers a cost competitive higher capacity upgrade from the OEM Glock magazines. It features an impact resistant polymer construction, easy to disassemble design with a flared floor plate for positive magazine extraction, and resilient stainless steel spring for corrosion resistance. This magazine is designed for competition with a dot matrix panel for mag identification and indicator windows to quickly asses round counts.
