Why so many non-matching mags?

[Norme]

To shift this discussion somewhat to my own area of interest, Imperial Navy Lugers, which have an even lower rate of matched mags than Army, particularly when one considers that each gun was issued with three, not two, numbered mags. My theory is as follows: Most of the world's Navies kept, and still keep, their small arms under lock and key (probably because of that nasty business with H.M.S Bounty). In the case of the Imperial Navy this would have meant that the guns were locked in a rack or case, while the rest of the rig, with two of the mags, would most likely have been hung on a hook or stuffed in a cubby. When a landing or boarding party was formed, an officer would have unlocked the guns and the men would have grabbed a gun and rig without regard to matching numbers. It wouldn't take long before guns, stocks and mags were well and truly mixed. Remember, it's just a theory. Regards, Norm
