I don't know if any of you guys remember this HalfLife mod called Fire Arms, but it allowed you to combine half used magazines into one, or a full magazine and then one with a lot less ammo in it. Add this and then an option to load specific mags from the gear screen and you'll have a solution.

Lol, reminds me of the first time I raided the NW airfield with a buddy. Everything went smoothly till he got greedy and decided to hit up the northern barracks as well and somehow fired his AKM on accident, attracting a horde of zombies and some snipers to boot :P I think I managed to kill one of the snipers though before the swarm got me.
