The bill aims to regulate pistol converters and convertible pistols in New York. A pistol converter is a device that enables a semi-automatic pistol to fire rapidly or automatically, and a convertible pistol is a semi-automatic pistol with a cruciform trigger bar that can be converted into a machine gun. The bill prohibits the manufacture, sale, and possession of machine guns and pistol converters, except for certain individuals such as military personnel, police officers, and licensed gunsmiths. It also imposes penalties on those who transport or ship machine guns, pistol converters, or other prohibited firearms without proper authorization. The bill takes effect 180 days after its enactment.
