Under 21, But Constitutionally Old Enough for a Hand gun ? DOJ Takes Aim at Age Ban

The U.S. Justice Department has concluded that a federal law preventing licensed firearms dealers from selling handguns to adults under the age of 21 is unconstitutional and cannot be enforced, marking a significant development in the ongoing legal debate over gun rights and age restrictions. In a legal opinion released on Friday, September 19, 2026, the Justice Department Office of Legal Counsel (OLC) said the federal restriction targeting 18- to 20-year-olds conflicts with the Second Amendment. The opinion concerns a federal provision that prohibits federally licensed firearms dealers from selling handguns to adults who have reached 18 but are not yet 21. According to the OLC analysis, the restriction does not withstand constitutional scrutiny under the Supreme Court modern Second Amendment frame work. A Shift in Federal Enforcement The opinion also signals a change in the Trump administration's approach to the law. The Justice Department indicated that the administration will not defend the restriction in court or prosecute cases based on violations of the provision. That position could have practical consequences for ongoing and future legal disputes involving the handgun sales restriction, particularly as courts have reached differing conclusions about whether the law is compatible with the Second Amendment. The Justice Department position, however, does not by itself erase the statute from federal law. The legal status of the provision remains tied to the broader judicial process and any future rulings by federal court. Supreme Court Decision at the Center of the Debate The dispute follows a landmark Supreme Court decision that significantly changed the way court evaluate firearm regulation. That ruling established a historical approach to Second Amendment questions, requiring court to consider whether modern firearms restrictions are consistent with the nation historical tradition of regulating weapons. The approach has subsequently generated litigation over a range of gun control measures, including restrictions based on age, location and the categories of people who may legally possess or purchase firearms. The Justice Department's latest opinion applies that constitutional framework to the federal handgun sales restriction affecting young adults. What Happens Next? The opinion could intensify the legal debate over whether the government can impose age based restrictions on hand gun purchases by adults between 18 and 20. Supporters of such restrictions have historically argued that additional safe guards for young adults can reduce access to firearms among a younger population, while opponents have argued that adults who are legally recognized as adults should not lose constitutional firearm rights solely because they are under 21. The Justice Department legal opinion now places the federal government on the side of the latter constitutional argument. The ultimate legal status of the restriction could still depend on federal court proceeding and, potentially, further consideration by the Supreme Court. For now, the September 19 opinion represents a notable shift in the federal government's position, a law designed to restrict handgun sales to 18 to 20 year old has been declared unconstitutional by the Justice Department Office of Legal Counsel, with the administration indicating that it will not enforce or defend the provision.
