Delaware files landmark lawsuit against Glock for enabling proliferation of illegal machine guns

Attorney General Kathleen Jennings today announced a civil lawsuit against arms dealer Glock, Inc. and Glock Ges.m.b.H. under the Keshall “KeKe” Anderson Safe Firearm Sales Act. The lawsuit alleges that the company has knowingly designed, marketed, and sold handguns that can be easily converted into illegal machine guns using so‑called “Glock switches.”

The design of Glock pistols allows them to be easily, quickly, and cheaply transformed into weapons capable of firing up to 1,200 rounds per minute using inexpensive conversion devices. Glock has known for decades that its design makes these conversions possible, yet has refused to adopt safety features that would prevent them. Instead, the company continued to market these products to civilians, even as law enforcement nationwide reported a surge in violence involving converted Glock handguns.

“For decades, some gun manufacturers have hidden behind the myth that their industry has no moral consequences, that their stake in our communities ends at the cash register, and that they are neutrals in the war between law enforcement and gun violence. Those days are over,” said Attorney General Kathy Jennings. “Our communities, and communities across America, are being terrorized by weapons with destructive power never intended or legal for civilian use. Glock knew. They could have acted. They chose profit over people.”

The complaint outlines:

  • A dramatic rise in crimes involving Glock handguns modified with switches, both nationwide and in Delaware.
  • Multiple seizures of illegally converted Glocks in Delaware, including
  • Allegations that Glock ignored warnings from federal authorities, declined to redesign its firearms, and failed to adopt reasonable controls to reduce unlawful use.
  • Evidence that Glock’s own marketing and social media content glorified fully automatic fire, despite such weapons being illegal for civilian purchase.

The State asserts five causes of action, including violations of Delaware’s firearm industry accountability statute and common‑law public nuisance. The lawsuit seeks an injunction barring Glock from distributing easily convertible pistols to civilians in the state; abatement of the public nuisance; and other relief, including restitution and damages. The lawsuit does not affect Glock sales to law enforcement.

Glock switches and other devices that convert semi-automatic firearms into fully automatic machine guns are illegal in Delaware. In 2025, Jennings co-led, and won, national litigation against the Bureau of Alcohol, Tobacco, Firearms and Explosives that defeated the agency’s plan to redistribute forced reset triggers—devices that convert semiautomatic rifles into fully automatic machine guns—that it had previously seized back into the state.
