Abstract
A magazine spring includes intermediate coils each having a first end portion, a second end portion, and a waist portion between the first end portion and the second end portion. The waist portion has a width that is less than a width of at least one of the first end portion and the second end portion. A magazine tube is also disclosed. In one example, the magazine tube is made of sheet metal and includes grip indentations formed along forward corners of the magazine tube. The magazine tube may also define locating ribs for blank cartridges. A magazine spring having the narrow waist portion can be included in the magazine assembly so that the spring clears the locating ribs.
