Relating to the prosecution of the criminal offense of the possession, manufacture, transport, repair, or sale of certain devices intended to modify handguns.

SB 1668 makes it a criminal offense to possess, manufacture, transport, repair, or sell certain devices designed to modify handguns to fire automatically more than two shots without reloading (like bump stocks). It also prohibits similar devices for machine guns, short-barrel firearms, explosive weapons, armor-piercing ammunition, zip guns, tire deflation devices, and improvised explosive devices. The law applies only to offenses committed on or after September 1, 2025, and exempts items already registered with federal authorities or classified as curios/relics by the U.S. Department of Justice. This directly affects individuals who own or distribute these specific firearm modification devices.
