When carrying a spare magazine in a pocket, backpack or range bag, dust, dirt and debris can easily find a way inside the mag and interfere with its function. Additionally, dropping an unprotected magazine can cause serious damage to the mag’s feed lips or body that makes ammo feeding difficult or impossible. Ammo Armor Magazine Covers keep magazines clean and provide essential impact protection, protecting shooters from the dangers of damaged ammo and magazine jams. This Magazine Cover is designed with a tapered opening that allows for quick and easy insertion of the magazine and features a compression fit to ensure mags stay covered and protected.

This Magazine Cover fits the following Ruger mags: Security-9®, Security-380®, Security-9® Compact, SR9c®, SR40c® & Ruger American® Pistol Compact. Made in the USA by Ammo Armor.
