These magazine carriers are the ones featured in Guns & Ammo Carbine Edition Magazine and are for the Glock 33rd magazines. They feature an extra deep pocket that prevents a fully loaded magazine from leaning out and away from your body. They also ride low and tight on your belt to avoid getting caught on anything. Definitely a must have for any competition shooting, hunting or just going to the range.
Also available for the Springfield Armory XD .40 S&W 20rd magazine
