This sheath not only works great for a pistol magazine, but it also fits folding knives (such as my LCC) perfectly. It is designed with a squeeze lock for the top flap, along with a heavy-duty belt loop that works with velcro to absolutely lock the sheath to your belt, or backpack, or any vertical or horizontal strap.
It is made of heavy-duty materials and designed for rugged use. It could also be used to carry a small flashlight, firestarting rod, or other similar sized outdoor products. You will enjoy this and find it very handy.
