The MAINSTAY™ Non-Slip Pocket Mag Pouch from Elite Survival Systems fits both single and double stack magazines. The silicone-coated outer shell offers unbeatable slip resistance and keeps the pocket mag pouch firmly in place, including when removing the mag. Superior materials ensure the IWB magazine holder will not flake or disintegrate over time. The Mainstay’s soft interior lining helps to protect the magazine and keeps out lint and other debris that can affect mag performance. Its lightweight water-resistant materials do not absorb moisture. Fits most single-stack and double-stack pistol magazines for 9mm, 40 S&W or .45 auto ammunition. Made in the USA by Elite® Survival Systems.
