Abstract A magazine for housing cartridges, preferably nine millimeter cartridges, is disclosed and includes, as part of the follower assembly, a spirally wound conforce spring unit, preferably comprising a plurality of separate but attached conforce springs. In a preferred embodiment the magazine includes a conventional in- length body, which has been modified by providing an elongated rib on the inside surface of a first side wall of the body. A wound portion of the spiral spring unit is located off-center and adjacent to an end portion of a follower body. An unwound portion of the spring unit is located adjacent to the first side wall of the maga- zine body. The rib acts to prevent contact between the unwound spring unit portion and the cartridges housed in the magazine. In a preferred embodiment, the follower body has a substantially compound support surface where- by two adjacent cartridges contact each other and the support surface of the follower body to prevent or reduce rotational-type movement of the follower body. In one embodiment of the magazine a number of latch areas are also provided so that the magazine can be used with different styles of firearms.
