摘要

Double stack magazines have a tubular body defining an elongated passage and a lower and upper end, a floor plate element connected to the lower end, an elongated separator element within the passage, a follower defining an aperture receiving the separator element and movable within the elongated passage, a spring within the passage having a first end contacting the floor plate, and having an opposed second end contacting and biasing the follower toward the upper end of the body. The separator may be a rod spaced apart from the body surfaces. The spring may be spaced apart from the separator element. The spring may be a coil spring having multiple winds, each encompassing the separator element. The separator element may be medially located in the body. The separator element may be positioned to define first and second stack passages between the left and right side walls and the separator element.
