Description

This is a factory Glock 21 13-round magazine, chambered in .45 ACP.

This Glock 21 magazine is the most reliable option for your G21 pistol. This Glock 21 mag will perform flawlessly even in the most extreme conditions, featuring a polymer body with full-length steel inserts. In addition, it features other signature Glock staples, such as an anti-tilt follower, steel spring wire, rear witness holes, and an impact-resistant base pad. What’s not to love? 

As with Glock factory magazines, their factory springs may be tough to load out of the box. However, loading and unloading a few times will help loosen the spring and become much more thumb-friendly. If you’re looking for even more thumb-relief, view our selection of magazine loaders. They’re convenient for lengthy range days or during the cold winter!

Please note that this Glock magazine fits other doublestack Glock pistols chambered in .45 ACP, such as the Glock 30.

Be sure to keep your Glock 21 running at peak performance with fresh mags. Pick up a few today!

There’s no substitute for mag capacity with these Glock 2113 round mags. You can get extensions to bring them to 25 rounds that’s a lot of 45 ACP. They fit very nicely in my Glock 30 S. Be responsible. Be safe and go bang bang.
