    Abstract: A gun magazine is provided having a magazine frame, a magazine base, a magazine follower located inside the magazine frame, a spring element located inside the magazine frame and configured to engage the magazine base and the magazine follower, and a pull element, such as a braided metal cord, coupled to the underside of the magazine follower and extending through an opening in the magazine base. A keeper element is attached to an intermediate location of the pull element, and a grip element is coupled to an end of the pull element, outside of the magazine frame. The grip element is grasped and pulled downward, thereby moving the magazine follower down in the magazine frame. The keeper element passes through a wide section of the opening and is then engaged with a narrow section of the opening, thereby holding the magazine follower near the bottom of the magazine frame.
