Plan the Heavy Sturm fighter was just plain too heavy with an extra weight of over 500 pounds. Not so much the armament as the protective armor around the cockpit, canopy, fuel tank, ammo storage. It was quite unwiedly in flight and the pilots were given the express directive not to engage enemy fighters if at all possilbe. this then was where the lighter and more nimble Bf 109G's were to come into play...........
