And large capacity magazines are this kind of ammunition device." "Guns not only cost us lives, but they also impose huge economic costs. Emergency rooms treat nearly 500,000 nonfatal gunshot injuries from assaults nationwide, costing an estimated $2 billion a year, half of which is borne by the public"
