Firearms and Ammunition - As introduced, requires TACIR to perform a study on the impact of this state's firearm laws on each county's firearm sales, criminal offenses, and use of firearms for self-defense, as well as identifying the similarities and dissimilarities between the impacts on each county. - Amends TCA Title 37; Title 38; Title 39 and Title 40.

SB 379 directed Tennessee's intergovernmental relations commission (TACIR) to study how state firearm laws impact county-level firearm sales, criminal offenses, and self-defense use. The study would identify similarities and differences in these impacts across all counties, requiring cooperation from state agencies. TACIR was required to complete the study and submit a report to lawmakers by January 1, 2026. The bill was introduced in February 2025 but withdrawn on December 1, 2025, and did not become law.
