Senate Bill 379, also known as House Bill 514, mandates the Tennessee Advisory Commission on Intergovernmental Relations (TACIR) to conduct a comprehensive study on the impact of the state's firearm laws across various counties. The study will focus on three key areas: firearm sales, criminal offenses, and the use of firearms for self-defense. TACIR is required to identify any similarities or differences in the impacts of these laws and will receive assistance from relevant state departments and agencies throughout the study process.

The findings from this study must be reported to each member of the General Assembly by January 1, 2026, and a copy of the report will also be provided to the legislative librarian, with the option for electronic delivery. The bill is set to take effect immediately upon becoming law, emphasizing the importance of public welfare in its implementation.
