HARTFORD, CT — GLOCK, Inc. filed a complaint in the United States District Court for the District of Connecticut on September 21, 2026, asking a federal judge to stop the state from enforcing its new ban on “convertible pistols.” The company filed the complaint together with a motion for a temporary restraining order and preliminary injunction, which are court orders that would freeze enforcement of the law while the case is decided.
The suit names the Connecticut State’s Attorneys and the Commissioner of the Connecticut Department of Emergency Services and Public Protection as defendants, according to GLOCK’s announcement. It seeks declaratory and injunctive relief, meaning a ruling that the law is unlawful and an order barring the state from enforcing it. The law at issue is Connecticut 2026 HB 5043, now Public Act 26-41.
GLOCK’s first argument is not about the Second Amendment. It is about the words on the page. The complaint maintains that the statute’s definition of “convertible pistols” is vague, ambiguous and unclear as to whether GLOCK pistols manufactured after October 1, 2026 can be sold in Connecticut. A criminal statute has to tell a dealer, a buyer and a police officer what is banned before it punishes them for it. According to GLOCK, this one does not.
The company says it tried to get an answer before it went to court. Customers, dealers and law enforcement agencies were asking GLOCK what the statute meant for them, and GLOCK says it sought clarification from the Connecticut Office of the Attorney General and the State’s Attorneys, to no avail. When the offices that will prosecute under a law decline to say what it covers, the people who have to comply with it are left with one option, and GLOCK took it.
The second argument is the constitutional one. GLOCK contends the law infringes on the Second Amendment rights of law-abiding Connecticut residents by prohibiting an entire class of lawfully made and sold handguns. The company says it is suing to gain clarity for Connecticut citizens and to safeguard the right of law-abiding citizens to choose the handguns they keep and bear for self-defense. These are GLOCK’s allegations, and the court has not ruled on any of them.
Connecticut Attorney General William Tong has already signaled the state will fight. In a statement released by his office, Tong described the statute as prohibiting the sale and importation of handguns that can be readily converted into fully automatic machine guns. “Connecticut’s commonsense gun laws are lawful and lifesaving. I will aggressively defend Connecticut against efforts to erode those commonsense laws that keep people safe on our streets and in our schools, houses of worship and businesses,” Tong said.
Set the two descriptions side by side and the dispute is plain. The state says it is banning handguns that can be readily converted into machine guns. GLOCK says the state cannot tell it whether its own pistols built after October 1 fall inside that definition. This is a design GLOCK says has been favored by military and law enforcement agencies worldwide since Gaston Glock brought the polymer-framed pistol to the United States in 1986, built with three internal safeties. Forty years on, according to the company, its legal status in one state is an open question that the state’s own lawyers would not close.
This is not the only Connecticut firearms ban in federal litigation. The Second Amendment Foundation has the state’s “assault weapons” rifle ban before the Supreme Court in Grant v. Rovella, and in January it filed a reply brief urging the Court to take the case and decide that AR-15-style rifles are in common use and therefore protected. SAF’s position there is that the Supreme Court has already said a firearm in common use for lawful purposes cannot be banned. GLOCK’s complaint targets a different gun, but a ban on an entire class of commonly sold handguns runs into the same question.
More from USA Carry:
For anyone who carries or plans to buy a Glock under a Connecticut pistol permit, the question of what this statute actually reaches is now in front of a federal judge. Part of a serious carry mindset is knowing what your state’s law says about the gun you carry, and right now the manufacturer of that gun says the state will not tell you.
I will continue tracking this case, including any ruling on GLOCK’s request for a temporary restraining order.
