Not Enforced
Federal prosecutors will no longer charge licensed dealers solely for selling handguns to otherwise law-abiding 18, 19, and 20-year-olds after a Justice Department legal opinion concluded the 1968 restriction violates the Second Amendment.
The Office of Legal Counsel issued the memorandum on September 17, 2026, and the department released it publicly the next day. The law itself remains on the books. What changed is criminal enforcement by the executive branch.
The opinion does not repeal the Gun Control Act, bind state governments, or automatically rewrite ATF forms and dealer guidance. Licensed dealers, state officials, and young buyers still face a patchwork of statutes, court rulings, and unanswered operational questions.
The 1968 Rule and How It Worked
Congress set two different commercial age floors in the Gun Control Act of 1968. Federally licensed dealers may sell rifles and shotguns to people 18 and older. They may not sell handguns or handgun ammunition to anyone they know or have reason to believe is under 21. Private, unlicensed transfers of handguns have long been treated differently under federal law; an 18-year-old could generally acquire a pistol that way in states that did not impose their own higher age.
The restriction was always aimed at commercial channels. It did not, by itself, make it a federal crime for an 18-year-old to possess a handgun obtained as a gift or through a private sale. Parents could also buy a handgun and transfer it. The practical effect was to keep most 18-to-20-year-olds out of gun-store handgun counters and the National Instant Criminal Background Check System pathway that dealers use.
That framework lasted nearly six decades. After the Supreme Court’s 2022 decision in New York State Rifle & Pistol Association v. Bruen, challengers argued the age cutoff could not survive the new historical-tradition test. Several lawsuits followed.
The OLC Opinion and Its Reasoning
Assistant Attorney General T. Elliot Gaiser wrote that 18-to-20-year-olds are part of “the people” protected by the Second Amendment. The opinion notes that 18-year-olds may vote, serve on juries, be drafted, and face adult criminal penalties, including capital punishment. Handguns, the Supreme Court has said, are the “quintessential self-defense weapon.” Blocking their purchase from licensed dealers therefore burdens a right the Amendment’s text covers and is presumptively unconstitutional.
OLC then asked whether the government could show a founding-era tradition of similar restrictions. It concluded the government could not. Militia statutes at the founding commonly required service beginning at 18 and required those men to furnish their own arms. The opinion found no comparable founding-era practice of barring legal adults from buying commonly used firearms. Later 19th-century age rules, OLC said, cannot override earlier evidence when they contradict it.
The operative sentence is narrow: sections 922(b)(1) and (c)(1) “may not be enforced to impose criminal penalties on dealers who sell handguns” to otherwise law-abiding adults in that age group. The memorandum binds Justice Department prosecutors. It is not a judicial injunction and does not erase the statute.
Courts Remain Divided
The Fifth Circuit struck down the federal handgun-sale ban in Reese v. ATF in January 2025, holding that 18-to-20-year-olds are among “the people” and that the government failed the Bruen historical test. The Justice Department did not seek Supreme Court review of that decision, so the ruling stands in Texas, Louisiana, and Mississippi. Other circuits have gone the other way. The Fourth, Tenth, and Eleventh Circuits have upheld similar age limits; the Third and Eighth have struck restrictions down. The Supreme Court declined several petitions on age-based firearm rules in June 2026 and has not resolved the split.
That leaves dealers and buyers in different legal environments depending on geography and on whether a state has its own 21-and-over statute. A district court in Connecticut recently upheld both federal and state handgun restrictions for this age group. Hawaii won a similar defense of its 21-year-old minimum. The national picture is still fragmented.
What Changes on Monday Morning — and What Does Not
Federal prosecutors have been instructed not to bring felony charges against a dealer for a sale that would previously have violated only the age provision, provided the buyer is otherwise eligible. Background checks, Form 4473 completion, prohibited-person bars, and waiting-period rules still apply. State laws still apply.
ATF’s published dealer guidance and the current Form 4473 still recite the old age rule. As of mid-September 2026, no new open letter, regulation, or form revision had appeared. Compliance lawyers advising Federal Firearms Licensees have therefore urged caution. A dealer who sells a handgun to a 19-year-old may no longer face a federal criminal prosecution for that fact alone, but license-revocation authority, civil penalties, and state charges remain possible until ATF and state regulators issue clear instructions. Some dealers will wait. Others in states without a 21-year-old handgun rule may begin processing those sales.
Private sales and intra-family transfers were already lawful in many places. The opinion’s main practical effect, if ATF follows through, is to open the licensed retail market and the NICS system to a cohort that previously used workarounds.
States Still Set Their Own Floors
The OLC memo does not preempt state law. Washington’s Initiative 1639 still bars pistol purchases by people under 21. Florida’s post-Parkland statutes impose a 21-year-old minimum for all firearms from licensed dealers. California, New York, Illinois, and several other states maintain 21-and-over rules for handguns or for all guns. Those statutes remain enforceable by state prosecutors and can still result in license action against dealers.
In states that simply tracked the federal commercial rule, the change is more immediate on paper. Indiana, like many states, has not layered an independent 21-year-old handgun purchase ban on top of the federal statute for most transactions. Even there, dealers will look first to ATF implementation and to whether local prosecutors treat the federal opinion as controlling. Concealed-carry licensing ages, campus rules, and private-property policies are separate questions.
Gun-control organizations argue the 18-to-20 cohort accounts for a disproportionate share of certain homicides and mass-shooting incidents and that the 1968 rule was a public-safety measure with a long pedigree. Gun-rights groups respond that adulthood for voting, military service, and criminal liability should include the right to acquire the most common self-defense firearm through the same regulated channel other adults use.
Reactions and the Next Moves
Everytown Law called the decision an abandonment of protections aimed at a high-risk age group. Giffords described it as the administration refusing to defend a statute Congress enacted. Brady said the opinion misreads the historical tradition of age-based regulation. Firearms Policy Coalition and other plaintiffs in the ongoing Reese litigation welcomed the legal conclusion but said they still want complete injunctive relief, including for ammunition, and clearer ATF guidance so dealers are not left guessing.
Congress has not amended the statute. A future administration could reverse the enforcement policy. Courts in circuits that have upheld the ban can still apply it in civil or licensing cases. Challenges to state 21-and-over laws will continue, now with an official Justice Department analysis they can cite. The Supreme Court can still take a case that cleanly presents the question.
For now the federal criminal threat against dealers for these sales has been withdrawn. The statute, the forms, many state codes, and the circuit split have not disappeared. Eighteen-to-20-year-olds who want a handgun from a licensed dealer will still need to confirm two things: whether their state independently forbids the sale, and whether the shop they walk into is willing to process it before ATF updates its instructions.
