S.3444 would ban gun dealers, after 12 months, from selling firearms not equipped with safety features which would “preclude an average five year old child from operating the pistol or revolver.” What exactly does that mean? The bill mandates that these “childproof guns” be equipped with adjustable triggers which can be set to 10 lbs. The guns would have to be designed so that they could not be operated by a small hand, according to the bill.
