So i was thinking as bullet shells fall, so why not clips?
As you reload the clip of the gun could fall out and a new one would appear after you are done reloading the gun.
Of course this would need 2 new Kv6 Files, but it'd be cool seeing the Smg/Rifle clips fall out of players guns.
(I Have no idea about shotguns though, i would guess not.)
The second Kv6 would be the gun without the clip while you are reloading, of course.
This could also indicate when an enemy player is reloading from a-far, so it could give you a chance to shoot back at them.
I don't see really a reason why not, it would be kind of neat to see aside from the gun shells flying out. And don't think the server would be flooded with them, they would disappear after a few seconds.
