Is it possible to make this if it doesn't exist already? Allows you to store partially-used pistol magazines. Would probably work the same way as Half-Life and the majority of every other shooter game where every mag you grab from your backpack is full of bullets, but then whenever you get down to your last bits of ammo, the last magazine just has whatever bullets you have left.

Like if you reload a USP in Half-Life 2, for example, if you have 7 rounds left in your inventory after depleting your mag, after reloading the mag only has 7 rounds in it. Or if it was a partial reload (like if you had 4 rounds left in your magazine before reloading), you'd have the 4 rounds in the mag plus the extra 7 that was left in your inventory, leaving you will a magazine of 11 rounds.

Anyone get what I'm saying?
