This is a factory 13-round magazine for Glock 21 pistols

These 13-round extended magazines feature the new style front cut for "SF" frames and have numbered witness holes for keeping track of capacity. They’re engineered for optimum fit & function, and designed to drop free when released.

ONLY fits 40 S&W ammunition and Glock 21 pistols.

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.

Factory Glock magazine, current production.
