Senate Bill 379 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. Additionally, TACIR is tasked with identifying any similarities or differences in the impacts observed in these areas. To facilitate this study, all relevant state departments and agencies are required to assist TACIR.

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