Abstract
A firearm magazine housing contains a spring to forcibly urge a follower with ammunition rounds stacked thereon toward an open end of the housing, thereby to facilitate delivery of the ammunition rounds into the firing chamber of a firearm. A follower support apparatus disposed within the housing supports the follower for movement in the housing, and permits the ammunition rounds to be stacked onto the follower independently of the spring.
