Magpul PMAG 21 GL9 - Glock pistol magazine is a 21-round magazine designed for 9mm double-stack Glock pistols, featuring a durable polymer construction for reliable operation and longevity. It meets the 140 mm (140MM) competition magazine overall length requirements and provides additional capacity without separate base extensions. Made in the USA.
The magazine incorporates key features of Magpul's PMAG design: a high-visibility controlled-tilt follower for improved feeding reliability, a long-lasting stainless steel spring resistant to wear and dirt, and an easily removable flared floor plate for cleaning. The floor plate's grooved edges provide better handling grip, and the capacity windows on both sides of the body indicate the fill level at 10, 15, and 21 rounds.
The magazine drops free from the firearm whether loaded or empty, facilitating smooth changes. The body features a molded-in paint pen dot matrix for magazine marking and load identification. The lightweight yet rigid polymer body withstands heavy use and retains its shape.
Compatibility includes full-size, compact, and sub-compact double-stack 9mm Glock models; in smaller frames, the magazine extends slightly below the grip. This solution brings Magpul's renowned usability to Glock: reliable feeding, easy maintenance, and clear capacity tracking.
