Silly gamers. This has already been addressed on the Steam Forums. It's a magic belt. First off, you notice when you put your Katana away, it goes on your right side, but you draw it from your left?
Here's what's happening.
Your belt isn't just any ordinary belt, it's a conveyor belt. Yes, you put the sword away on your right. But while you're using your guns, your sword is slowly meandering around your waist, stopping at the left side for you to draw it again.
It's a standard in all FPS games. The conveyor belt also automatically grabs any discarded magazines, removes any remaining bullets and replenish your other mags.
Can't leave home without it!
And since you can't look down and see your own waist, you can't prove this to be wrong! Argument ended. Magazines are disposed of properly into your magic belt...
