The bill amends Chapter 11-47 of the General Laws, titled "Weapons," to introduce new definitions and clarify existing terms related to firearms and weaponry. Key insertions include definitions for "3D printing process," "binary trigger," "bump-fire stock," "electronic dart gun," and "stun gun." The definition of "firearm" is modified to encompass a broader range of weapons, eliminating previous exclusions for instruments designed for non-weapon purposes. Additionally, the bill updates the definition of "ghost gun" to refer specifically to firearms without a unique serial number and clarifies what constitutes an "undetectable firearm." The bill also streamlines language by deleting phrases that previously excluded certain instruments from being classified as firearms, thereby enhancing clarity and organization.

Furthermore, the bill introduces a new section, 11-47-42, which prohibits the carrying or possession of specific weapons, such as blackjacks and slingshots, while lifting the prohibition on stun guns. It allows individuals aged eighteen and over to purchase and possess stun guns and electronic dart guns, with a strict prohibition on sales to minors. The legislation establishes penalties for violations, including felony charges for selling to minors or using these weapons in crimes against police officers. Increased penalties are also outlined for violations committed while incarcerated. Overall, the bill emphasizes responsible ownership and use of stun guns and electronic dart guns, ensuring that individuals prohibited from possessing firearms are also restricted from owning these devices, and it is set to take effect upon passage.
