Had this issue two times.
found an AKM barrel magazin with 75 rounds. While drinking / Door opening i pressed use button and choosed accidentally "Switch magazin XY" As i had not enough space in my inventory, the magazin dropped on the flor and glitched through the floor / Ground to nowhere.
Was searching the whole arrea but was unable to find it anymore.
Switch Barrel magazine with "f-Button" while having not enough space left inside the invenory.
AKM 75 round mag will disappear when reloading using F key if there is no 4x4 slot available in inventory.
