Delaware Supreme Court Reinstates 21-and-Older Firearm Purchasing Law

Gun rights organizations argue that 18-year-old citizens hold full constitutional rights and cannot be categorically barred from purchasing firearms for self-defense. State officials maintain that legislative bodies retain the authority to enact age-based safety regulations to curb violence among young adults.[2][3]

On September 9, 2026, the Delaware Supreme Court intervened in that exact dispute, reversing a lower court's injunction and reinstating a state law that restricts the purchase of most firearms to individuals 21 and older.[1][4][6]

The statute, originally passed by the Delaware General Assembly in 2022, raised the minimum purchasing age from 18 to 21. It applies to three primary categories of firearms—handguns, shotguns, and rifles—while carving out specific exemptions for active-duty military personnel, law enforcement officers, and individuals holding valid concealed carry permits.[2][5]

The law's enforcement was halted when a lower state court judge issued a preliminary injunction. That court determined the age restriction likely violated Article I, Section 20 of the Delaware Constitution, which states: "A person has the right to keep and bear arms for the defense of self, family, home and State, and for hunting and recreational use."[3][6]

The state appealed the injunction, arguing that the lower court misapplied the legal standard for constitutional scrutiny and failed to account for historical precedents regarding age limits. The Delaware Supreme Court agreed, lifting the hold and allowing the Department of Justice to resume enforcing the age limit immediately.[1][2]

The Delaware ruling arrives amid a fractured national legal landscape regarding age limits for firearms across the 50 states. Following the U.S. Supreme Court's 2022 decision in New York State Rifle & Pistol Association v. Bruen, federal and state courts have struggled to determine whether restricting 18-to-20-year-olds aligns with the nation's historical tradition of firearm regulation.[3]

Several federal appellate courts have reached conflicting conclusions on similar state laws. The differing interpretations of the Bruen framework have created a patchwork of regulations, with some jurisdictions striking down age limits and others upholding them as permissible safety measures.[4]

The Delaware Supreme Court's procedural ruling does not end the underlying lawsuit, but it shifts the immediate balance of power back to the state. The case now returns to the lower court for a full trial on the merits, where plaintiffs will have to overcome the higher court's initial assessment to permanently strike down the statute.[2][6]
