Why the model tagged it this way: The bill adds pistol converters and convertible pistols (semi-automatic pistols that can be readily altered into machine-guns) to the list of prohibited items under New York's penal law, criminalizing their manufacture, transport, shipping, and sale/disposition as class D felonies (with narrow exceptions for authorized military, law enforcement, and licensed dealers/gunsmiths). It also expands the definition of 'machine-gun' to include equipped convertible pistols. These provisions impose new restrictions on specific firearm accessories and certain semi-automatic pistols.
