18 vs. 21 Purchase Age: Where It Stands in 2026

Adults aged 18 to 20 can vote, sign contracts and serve in combat, yet since 1968 federal law (18 U.S.C. 922(b)(1) and (c)(1)) has barred licensed dealers from selling them handguns or handgun ammunition. Long guns can be bought from a dealer at 18 under federal law, and private handgun sales to adults 18 and older are not barred federally. Gun-rights advocates have long argued this age line has no basis in the founding-era tradition, when militia laws required 18-year-olds to serve and to bring their own arms.

The courts are split. In Reese v. ATF (January 30, 2025) the Fifth Circuit held the federal handgun sales ban unconstitutional, and a January 27, 2026 judgment protects covered plaintiffs in Texas, Louisiana and Mississippi. The Fourth Circuit upheld the same law in McCoy v. ATF (2025), and the en banc Eleventh Circuit upheld Florida’s under-21 purchase ban in NRA v. Bondi (March 2025). On June 30, 2026 the Supreme Court declined to hear both McCoy and NRA v. Glass, leaving the split in place.

Then, on September 18, 2026, the Justice Department released an Office of Legal Counsel opinion concluding the federal ban is unconstitutional as applied to law-abiding 18-to-20-year-olds and may not be enforced with criminal penalties against dealers who sell to them. The statute and ATF’s regulation (27 CFR 478.99) are still on the books, and as of this update ATF had not issued written guidance to dealers. Meanwhile some states moved the other way: Virginia raised its handgun purchase age to 21 effective July 1, 2026.

Key Facts

• Federal law: 18 U.S.C. 922(b)(1) and (c)(1) bar dealer handgun sales to buyers under 21; long-gun dealer sales are allowed at 18.
• January 30, 2025: Reese v. ATF, 127 F.4th 583 (5th Cir.), struck the federal ban; DOJ did not seek Supreme Court review.
• 2025: McCoy v. ATF, 140 F.4th 568 (4th Cir.), upheld the federal ban; cert denied June 30, 2026.
• June 30, 2026: cert also denied in NRA v. Glass (Florida’s under-21 ban on all firearm purchases).
• September 17-18, 2026: DOJ Office of Legal Counsel opinion and announcement that the dealer handgun ban cannot be criminally enforced against sales to law-abiding adults 18 to 20.
• Virginia HB 1525 (2026): handgun purchases by those under 21 made a Class 1 misdemeanor, operative by July 1, 2026, with limited military and law enforcement exceptions.

What Gun Owners Should Know

• The DOJ opinion is an enforcement position, not a court ruling or a repeal; many dealers will wait for written ATF guidance before selling handguns to buyers under 21.
• State law still controls: states such as Florida, Virginia and others set their own minimum ages, and a dealer must follow both.
• Buyers under 21 face enhanced NICS checks that can take up to 10 business days.
• Young adults should keep up with training and safe-handling skills; After Action.net lists training resources.
