The bill introduces amendments to Chapter 11-47 of the General Laws, which pertains to "Weapons," by updating definitions and regulations related to firearms, stun guns, and other weapons. It adds new definitions for modern firearm-related devices such as "3D printing process," "binary trigger," "bump-fire stock," "ghost gun," and "undetectable firearm," and broadens the definition of "firearm" to encompass a wider array of weapons and components. The bill also renumbers existing definitions to accommodate these insertions, for instance, changing the numbering of "sell" from (17) to (18) to include "stun gun" as (17). It aims to address the challenges posed by firearms that are difficult to detect and includes provisions related to the carrying of pistols, revolvers, and stun guns, requiring a license or permit for such activities, with certain exceptions.

Furthermore, the bill outlines the legal consequences of carrying or possessing various weapons, including stun guns, and sets age restrictions for their purchase and possession. It criminalizes the sale of stun guns to minors and their use in criminal activities or against law enforcement officers. The bill also establishes a process for individuals to request reconsideration of a denied license or permit to carry a stun gun, with a timeline for an in-person meeting and a subsequent decision. If the denial is upheld, the individual has the right to appeal to the superior court for a trial de novo. The appeal process is confidential, and the court may award attorney's fees and costs to the applicant if the denial lacked a justifiable basis.
