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.
