The bill amends Section 11-47-2 of the General Laws in Chapter 11-47 entitled "Weapons" to include new definitions and modify existing ones. Notably, it introduces the term "crime gun," which is defined as any firearm used in a crime or suspected by law enforcement of having been used in a criminal offense. The bill also includes definitions for terms such as "3D printing process," "binary trigger," "bump-fire stock," and "ghost gun," among others. These definitions are crucial for the legal categorization and regulation of firearms and firearm components, particularly in the context of criminal investigations and law enforcement.

Additionally, the bill mandates that in the case of an offense where a "crime gun" is seized, the arresting or investigating police department must submit the firearm or at least two test-fired cartridge cases to the state crime laboratory, the Federal Bureau of Alcohol, Tobacco, Firearms and Explosives (BATF), or any qualified law enforcement agency for forensic ballistics examinations. These items must also be entered into the National Integrated Ballistic Information Network (NIBIN). Furthermore, any spent shell casings recovered at a crime scene must be submitted to the NIBIN as soon as practicable. The bill is set to take effect upon passage, emphasizing the importance of timely and accurate ballistics testing and tracing in criminal investigations.
