Firearms and Ammunition - As introduced, requires a gun dealer to ensure that three days have passed since the transaction was initiated by the purchaser before transferring a firearm to a purchaser if the purchaser is older than 17 but younger than 21. - Amends TCA Title 39, Chapter 17, Part 13.

SB 1104 requires gun dealers in Tennessee to wait three days before transferring a firearm to a purchaser aged 17 to 20, starting from when the transaction is first initiated by the buyer. This law directly affects gun dealers and young adult purchasers in that age range. The key provision mandates a mandatory waiting period for these specific transactions, as amended to Tennessee Code Section 39-17-1316(c)(5). The bill takes effect July 1, 2025, applying to all firearm transfers meeting the age criteria on or after that date.
