When spawning in with a gun from a loadout, you are not able to reload the gun by holding r until the mag is either empty, you drop the gun and pick it back up, or you use tab and drag the mag out of the gun. This problem could cause issues if someone is in combat, and their mag gets low, and they want to put a fully loaded mag into the gun. Being in combat they will want to hold r to quickly perform this action and not have to use the inventory Ui to do the action.
