We treat guns just like magazines. When you load a magazine into a gun, we transfer the ammo list from the magazine to the gun, make a note of the magazines index number on the gun, then delete the magazine. Since every item uses the same OBJECTTYPE structure, this is a very simple procedure.

And I'm suggesting "deleteing" the magazine object once it's loaded into a gun because there's really no reason to store any of the magazines object data. When we eject the magazine from the gun, we simply create an object using the previously stored magazine index number and transfer the gun's ammo list to the new magazine item.

3- Do we use a single "generic magazine" item for empty mags or just use the "mag types" for all mags? The upside of a single "generic magazine" is that you could create large stacks of magazines for transport, which reduces inventory management. But it would mean we'd need a way to tell the code why kind of mag we wanted when we removed one from the stack. And you also run into the unrealistic ability of getting an 8rnd .45ACP mag from a drop and "converting" it to a 100rnd 5.56 C-Mag.

Well, guess it's pretty inefficient to drag the mag around for something banal like a few extra points on jam rate then.
