Abstract: A firearm magazine cover is disclosed for encircling a firearm magazine. The firearm magazine cover comprises a sleeve defining a front wall, a primary side wall, a secondary side wall, and a rear wall extending between an upper edge and a lower edge. An upper aperture is in the upper edge of the sleeve for receiving the firearm magazine. A lower aperture is in the lower edge of the sleeve for protruding the firearm magazine beyond the sleeve. The sleeve is constructed of an elastic rubber for defining a grasping collar. The grasping collar permits grasping the firearm magazine during engagement with the firearm and firmly grasping the firearm magazine during disengagement with the firearm.
