Our pocket magazine holster is the perfect way to carry spare ammo and we have been using these for years. It is made using thin Kydex and is designed to keep the magazine in an upright and ready in the pocket. Too many times we found our magazine floating around in the pocket and full of pocket lint. To draw simply grasp the magazine and draw out of the pocket catching the holster on the pocket corner and it will come out clean everytime. We feel this is the easiest and most convenient way to carry your spare ammo and it “just plain works”.
