    Abstract: A case to hold spare ammunition magazines for a machine pistol. The case includes a pocket dimensioned to accommodate at least two magazines with the left side of one facing the right side of the other, and with the flange end of each protruding from the pocket. The case has a first strap that can be closed to cover the protruding flange end of the first magazine, and a second strap than can be closed to cover the protruding flange end of the second magazine. The second strap has a set back portion of its inner edge such that when the first strap is opened, the second strap allows greater access to the protruding end of the first magazine. The case also has a divider that separates the pocket into two portions, one to accommodate each magazine, and that provides a gap between the protruding ends of the magazines.
