Matching magazine question

[gunbugs]

It was my understanding that when the Germans were disarmed during surrender and/or capture, that the pistols were thrown in one pile, and the magazines in another, as the weapons were cleared of ammo. Then, usually, when an enterprising GI would want a "German Luger" to take home, they would pick a pistol out of one pile, and a mag out of the other, of course not paying any attention to "matching numbers", thus contributing to the great number of mismatched mags.
