Geez - your internal build may be working, but no servers on the current exp. branch version EVER spawn magazines in weapons. This is true on both community & official servers. I have seen literally hundreds of spawned weapons in the current build and not a single one of them had a magazine attached. Note - this is purely to do with the way loot is being spawned in. If a player drops a weapon that they have loaded a magazine into themselves, another player finding that weapon on the ground will see the magazine in the gun. Weapons spawned through the CLE never have magazines in them though.
