It is never hand held, the weight of the ammo and battery it requires would keep you from going very far, then when you fired it the recoil of up to 6000 rounds a minute would put you on your back. Also since it burns ammo so fast someone would have to carry a few thousand rounds for you, not to forget the fact that the battery is only good for 2000 rounds meaning you would have to bring a few extra batteries (which aren't light), the combined time of reloading and switching batteries makes the user combat ineffective... especially since he would LITERALLY be spraying rounds everywhere.
