Glock Mag
What can you say? OEM 33 rounder, works like it should!
This is a factory 33-round magazine for Glock 9mm pistols
These 33-round extended magazines (31 round stick with a factory +2 extension) feature numbered witness holes for keeping track of capacity. They’re engineered for optimum fit & function, and designed to drop free when released.
ONLY fits 9MM ammunition and Glock 17, 18, 19, 19x, 26 and 34 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.
