I was curious as to how professional operators and LEO’s label, identify, and manage their carbine magazines. I have seen various ways including white paint Sharpies, engraving, and color coding. I would imagine that since you have multiple mags, all with various loads (target, training, etc) that the mags would be marked differently via a combination of numbers, letters, and possibly color to ID them quickly. I apologize if there is already a detailed thread on this and if so please don’t hesitate to direct me.
