How Old Do You Have to Be to Buy a Pistol in Tennessee?

To buy a pistol in Tennessee, you have to be 21 if you’re buying from a licensed firearms dealer and 18 if you’re buying from a private seller. Both numbers come from federal law; Tennessee doesn’t add its own higher age on top. The gap between the two is where most of the confusion lives, and the rest depends on where you buy, what ID you bring, and whether anything in your background triggers a closer look.

Buying From a Licensed Dealer

Federal law prohibits any licensed dealer from selling a handgun or handgun ammunition to anyone under 21.¹ Tennessee’s dealer-sales statute, TCA 39-17-1316, reinforces the same rule by prohibiting sales to anyone “ineligible to receive firearms under 18 U.S.C. § 922.”² The 21-year threshold applies whether you walk into a brick-and-mortar shop or buy online and have the pistol shipped to a dealer for transfer.

You’ll sometimes hear that “you can buy a gun at 18 in Tennessee.” That’s true for rifles and shotguns from a dealer, where the federal minimum is 18.³ It is not true for handguns.

Buying From a Private Seller

Federal law prohibits unlicensed persons from transferring a handgun to anyone they know or have reasonable cause to believe is under 18.⁴ Tennessee does not raise that floor. An 18-year-old who is otherwise allowed to possess a firearm can legally buy a pistol from a private party in the state.

Private sellers in Tennessee are not required to run background checks. They are still prohibited from knowingly transferring any firearm to someone the law bars from having one, including convicted felons, people under qualifying protective orders, and anyone who has been adjudicated mentally defective.¹ A Tennessee Attorney General opinion has confirmed that occasional private sales between individuals not engaged in the firearms business are exempt from federal licensing and background check requirements.⁵

Many private sellers ask to see a Tennessee handgun carry permit before completing a sale. A permit shows the buyer previously passed a background check, which gives the seller some practical cover. It isn’t a legal requirement.

One boundary matters even in a casual deal: you cannot privately transfer a handgun to someone you know or reasonably believe lives in another state. Interstate private handgun transfers have to go through a licensed dealer.¹

Extra Background Check if You’re Under 21

The Bipartisan Safer Communities Act, signed in 2022, added an extra layer of scrutiny for any firearm buyer under 21 purchasing from a licensed dealer. When the dealer contacts the National Instant Criminal Background Check System, the system also checks the buyer’s state criminal history repository, juvenile justice records, mental health adjudication records, and local law enforcement records.⁶

NICS has three business days to tell the dealer whether there’s cause to investigate a potentially disqualifying juvenile record. If nothing is flagged, the sale can proceed. If something comes up, the system has up to 10 business days total from the dealer’s initial contact to issue a final determination, and the dealer cannot complete the transfer during that window. This review runs on top of Tennessee’s standard TICS background check.

ID You’ll Need at the Counter

Tennessee law requires every buyer purchasing from a licensed dealer to present at least one current, valid piece of photo identification that shows the buyer’s date of birth. The ID must be issued by a government authority and must be of a type commonly used to identify individuals.² A Tennessee driver’s license or state ID card usually does the job.

If your photo ID doesn’t show your current residential address, you’ll need a second current government-issued document that does. The Brady Act requires the identification to bear the buyer’s name, photograph, date of birth, and residence address, and a combination of documents is acceptable.⁷

Active-Duty Military

If you’re active-duty military stationed in Tennessee, your permanent duty station establishes your state of residence for firearm purchase purposes. You can satisfy the ID requirement by presenting your military ID card along with official orders showing your permanent duty station is in Tennessee, even if your off-base home isn’t on the installation.⁷

Non-Citizens

Lawful permanent residents can purchase firearms with the same documentation requirements as U.S. citizens, plus a valid Permanent Resident Card. Nonimmigrant visa holders are generally prohibited from possessing firearms under federal law unless they qualify for a specific exception, such as holding a valid U.S. hunting license, entering for lawful hunting or sporting purposes, or serving as a foreign law enforcement officer on official business.⁸

Possession Under 18

Federal law makes it illegal for anyone under 18 to possess a handgun, with a short list of exceptions. A juvenile may temporarily possess a handgun for employment, ranching or farming activities, target practice, hunting, or a firearms safety course, provided they have prior written consent from a parent or guardian who is not themselves prohibited from possessing firearms.¹ Other exceptions cover members of the Armed Forces or National Guard acting in the line of duty, inheritance of title (though not possession), and self-defense against a home intruder.

An adult who transfers a handgun to a juvenile outside those exceptions faces up to one year in federal prison. If the adult knew the juvenile intended to use the handgun in a violent crime, the penalty rises to up to 10 years.⁹

Carrying What You Just Bought

The age to buy and the age to carry aren’t the same. Tennessee allows permitless carry of a handgun for adults who are legally allowed to possess a firearm, and the minimum age for permitless carry is 18, following a 2023 settlement in which the state attorney general’s office agreed not to prosecute 18- to 20-year-olds for carrying without a permit. Tennessee also offers an enhanced handgun carry permit for those 21 and older who want formal documentation of their right to carry, which is recognized in many other states through reciprocity agreements.¹⁰

So an 18-year-old who buys a pistol privately in Tennessee can legally carry it, but can’t walk into a dealer to buy another one until 21, and can’t get the enhanced permit until then either.
