Last updated September 2026 · By Nick Hall, tracks federal gun law and ATF dealer rules for USA Gun Shop readers
Quick take: The Justice Department’s Office of Legal Counsel says the federal law barring gun dealers from selling handguns to 18, 19 and 20 year olds violates the Second Amendment, and DOJ will not prosecute dealers under it. The statute is still on the books, though, and state age limits still apply.
- What happened: On September 17, 2026, the Office of Legal Counsel concluded that federal law cannot be used to criminally punish dealers who sell handguns to law-abiding adults aged 18 to 20.
- Why it matters: Since 1968, a licensed dealer who sold a handgun to a buyer under 21 risked a federal felony charge and the loss of the dealer’s license.
- What’s next: The DOJ announcement came with no revised Form 4473 and no new ATF dealer instructions, so the practical rollout is still ahead.
- Who to watch: ATF, which writes the dealer rules, and the 17 states plus the District of Columbia whose own age laws the opinion lists and leaves untouched.
Most federal gun policy news is either a proposed rule that takes two years to matter or a lawsuit that takes five. This one is neither. It’s the Justice Department telling itself it will not enforce a felony statute Congress passed in 1968, and it raises the question every 19-year-old shooter is asking this week: can I walk into a gun shop and buy a pistol?

What the OLC Opinion on 18-20 Handgun Sales Actually Says
The opinion is a 49-page memorandum for the Attorney General, signed by T. Elliot Gaiser, the Assistant Attorney General who runs the Office of Legal Counsel. It is dated September 17, 2026, and DOJ published the full OLC opinion with a press release the next day.
It targets two provisions of the Gun Control Act. Section 922(b)(1) of Title 18 bars a licensed dealer from selling any firearm other than a rifle or shotgun, or ammunition for one, to a buyer the dealer knows or has reasonable cause to believe is under 21. Section 922(c)(1) closes the mail-order route by requiring a sworn statement that a buyer who does not appear in person is 21 or older.
OLC ran both through the Bruen test as the Supreme Court restated it this year in its Wolford decision. Step one: adults aged 18 to 20 are part of "the people," handguns are arms, and a purchase ban restricts keeping them, so the law is presumptively unconstitutional. Step two: OLC found no founding-era tradition of stopping legal adults from buying guns, and pointed out that militia laws at the founding required service from age 18, with enrollees furnishing their own arms.
Gaiser put it plainly in the release: "Eighteen-year-olds may vote, serve on juries, be drafted, and face adult criminal penalties, including capital punishment." The opinion itself opens with a real example, an 18-year-old who shot skeet for the United States at the Tokyo Olympics and whose purchase of a pistol from a dealer would have been a federal felony for the dealer.
What the Opinion Does Not Do, and Why That’s the Whole Ballgame
An OLC opinion is legal advice to the Attorney General. It tells the Justice Department how it will use its own prosecutors. It is not a court judgment, it doesn’t strike anything from the federal code, and Congress hasn’t changed a word of 922(b)(1), which still reads "less than twenty-one years of age."
The opinion is narrow on purpose. It closes with a list of what it doesn’t reach: the ban on handgun possession by anyone under 18 in 922(x), the extra background-check investigation Congress set for buyers under 21 in 922(t)(1)(C), the prohibited-person rules in 922(g), and dealer sales to anyone under 18.
OLC says it outright: "Our opinion today does not foreclose litigation on this topic, as numerous states, which are not bound by our opinions, have similar age restrictions." Its own footnote lists age statutes in 17 states and the District of Columbia, including New York, Florida, Illinois, Hawaii, Massachusetts and California, where Penal Code section 27505 still governs California gun sales to young adults.
And federal law itself points dealers at those state rules. Section 922(b)(2) makes it a federal crime for a dealer to sell a gun where the buyer’s purchase or possession would violate state law or a published local ordinance. Before you drive to the counter, check your own state in our state-by-state gun law directory.
Nothing in the opinion orders a dealer to make the sale, either. Its conclusion is deliberately limited: the statute "may not be enforced to impose criminal penalties on dealers who sell handguns" to law-abiding adults. A shop that wants to keep a 21-and-over policy for handguns can keep it.
Where ATF and the Form 4473 Stand
This is where the rollout gets messy. The DOJ release did not come with a revised Form 4473 or with new ATF dealer instructions. The age rules also live in ATF regulations, which OLC cites as sections 478.96(b), 478.99(b) and 478.124(a) of Title 27, and OLC notes that a number of those regulations are currently under reconsideration by ATF.
One pending ATF proposal would formally let parents buy firearms for their children until the children turn 21. OLC says that change doesn’t affect its analysis, because it does nothing for a young adult buying a gun for himself.
My read: the counter is where this lives or dies. The opinion’s conclusion speaks to criminal penalties, and it does not separately address license revocation under 923(e), the risk that keeps shop owners up at night. Expect a lot of dealers to wait for ATF paperwork before they ring up a pistol for a 19-year-old. I would.
How the Courts Split on Under-21 Handgun Purchases
OLC is picking a side in a real split among federal appeals courts. The Fifth Circuit struck down this same federal age restriction in its 2025 Reese decision, a ruling that binds federal courts in Texas, Louisiana and Mississippi.
The Fourth Circuit went the other way in 2025, sustaining the federal age restrictions in the McCoy case. The full Eleventh Circuit upheld Florida’s ban on gun purchases by anyone under 21 the same year.
OLC says those decisions can’t be reconciled with the Supreme Court’s 2026 clarifications in Hemani and Wolford, so it declined to let them control its advice. That’s the federal government’s own lawyers taking the young adult side of a fight in which ATF was the defendant in both Reese and McCoy.
Can an 18-Year-Old Buy a Handgun at a Gun Shop Now?
Short answer: maybe, depending on your state and your dealer. Federal criminal exposure for the dealer is off the table as DOJ sees it. State law is not, the dealer’s own policy is not, and the federal background check still runs on every dealer sale.
Rifles and shotguns were never covered by the federal under-21 handgun rule, so a long gun from a dealer has been legal at 18 under federal law all along. For a handgun, call the shop first, confirm it will sell to you, then pick from the best handguns on the market.
The statute didn’t change. The prosecutor did. Until ATF catches up, that’s the whole story.
Frequently Asked Questions
Can an 18-year-old buy a handgun from a gun store now?
Under federal law, the Justice Department says it will not prosecute a licensed dealer who sells a handgun to a law-abiding adult aged 18 to 20. The statute is still on the books, state age limits still apply, and a dealer can still decline the sale.
What is an Office of Legal Counsel opinion?
The Office of Legal Counsel gives legal advice to the Attorney General and the executive branch, and its opinions guide how the Justice Department enforces federal law. An OLC opinion is not a court ruling, it does not bind the states, and it does not change the text of a statute.
Which federal laws does the DOJ opinion cover?
It covers 18 U.S.C. 922(b)(1) and 922(c)(1), the provisions that bar licensed dealers from selling handguns to buyers under 21. It concludes they may not be enforced to impose criminal penalties on dealers who sell handguns to law-abiding adults aged 18 to 20.
Does the opinion override state age limits on handgun purchases?
No. OLC says the states are not bound by its opinions, and it lists age restrictions in 17 states and the District of Columbia, including California, New York and Florida. Federal law also bars a dealer from making a sale that would violate the buyer's state law.
Can 18 to 20 year olds already buy rifles and shotguns from a dealer?
Yes. The federal under-21 rule has always applied to handguns and handgun ammunition, not rifles and shotguns, so federal law has allowed dealer sales of long guns to buyers 18 and older. State law can still set a higher age.
Does the opinion cover buyers under 18?
No. OLC expressly does not address sales to anyone under 18 or the separate federal ban on handgun possession by juveniles in 922(x). Those rules are unchanged.
Did Congress change the federal handgun purchase age?
No. The text of 922(b)(1) still sets the handgun age at twenty-one. The change is in how the Justice Department says it will enforce that text, not in the law itself.
Have courts ruled on the federal under-21 handgun sales ban?
Yes, and they disagree. The Fifth Circuit struck down the restriction in its 2025 Reese decision, while the Fourth Circuit upheld it in the McCoy case. OLC sided with the Reese view.
