The present disclosure provides a method of creating a visible indicator upon a firearm magazine. The method may comprise fabricating a plurality of rectangular matrices of divots on an exterior surface of the magazine, the divots having concave surfaces, each matrix comprising a plurality of rows of divots and a plurality of columns of divots. A first divot of a first row is also a first divot of a first column, the first divot forming a substantially straight line with each other divot of the first column, and a first divot of a second row is also a second divot of the first column. The method may then comprise marking, with paint or ink, at least one of the divots. |
