Glock magazines come with a very strong spring rate from the factory to ensure reliability in the toughest of conditions. Sometimes, magazines are found to be a little bit difficult to load at first. However, after a few times loading and unloading, the springs break in nicely and it becomes much easier to load.

We recommend using a magazine loader to ease the loading process.

For added strength and durability factory Glock magazines are steel lined on the interior with a crack resistant polymer body. This increased durability gives officers, military members, and dedicated citizens the confidence that there will be no issues under heavy training.

Trusted by military and law enforcement from all around the world, Glock factory magazines are the gold standard—and top shooters never trust anything less.
