Abstract: A magazine accessory includes a magazine pouch including a body having an open end for inserting or removing therethrough a magazine. An elastic retention device is pivotally coupled to the body at a pivot so that the elastic retention device can be positioned over the open end. The elastic retention device is constructed of an elastic cord with a stiffening layer, such that the elastic cord can be pulled over the magazine and press against the magazine to retain the magazine in the body of the magazine pouch. The stiffening layer keeps the elastic retention device pivoted away from the magazine when the elastic retention device is pivoted away from the magazine towards a side of the body.
