[-CaRRoT]

You don't need an attached object if you were already shooting, you only attach the object if you have 0 ammo, so the 2 scenarios you'd do that is that if you give someone a gun with no ammo, then you'd attach the object, or if you run out of ammo while shooting, you'd attach the object. Other than that, make sure to deattach it while having a gun with ammo.
