Glock Factory Magazine 43X, 48 (10rd)
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.
