Glock Factory Magazine 19X, 17, 34 (19rd)

Glock magazines are engineered with a robust spring rate right out of the factory, guaranteeing unparalleled reliability even in the harshest conditions. Initially, some users may find the magazines slightly challenging to load. However, with a few cycles of loading and unloading, the springs gradually break in, resulting in smoother and easier loading experiences. All Glock magazines are made of a crack-resistant polymer and are steel lined. These 19X mags are fitted with a +2 extension giving you  19+1 in the either a 17, 34 and of course, the 19X.
