Save your money - Glock Magazine Pouch

Bought this for a Glock 23 mag. . . .if you force the mag into it, it'll fit. Just hope you don't need the mag in a hurry because it's next to impossible to get out. The top of the mag will fit into the holder but this leaves it ready to fall out. Once you try to seat the mag in the holder appropriately, then you have the issue of getting the mag out when needed.
