These Glock Factory Magazine are designed to work. Double Stacked and Staggered for Maximum Capacity. We carry a diverse selection from high capacity to standard per model. Check your state laws and be sure you can own the magazines you are purchasing.
*Gen 4 magazines must be used in Gen 4 guns only if the magazine release is switched from the left side to the right side (for left-handed shooters). In any other case all previous generation magazines will fit the Gen 4 and all Gen 4 magazines will fit all Glocks from previous generations.
