Glock, Inc. v. Griffin

Where the case stands

Connecticut's HB 5043 makes it a class D felony, from October 1, 2026, to import, advertise or sell a "convertible pistol," defined as "any semiautomatic pistol with a cruciform trigger bar that can be readily altered by hand or with a common household tool so that the pistol can be readily converted into a machine gun" with an attached converter — a definition that reaches Glock and Glock-pattern pistols. On September 21, 2026, Glock, Inc. sued the Chief State's Attorney, the state's attorneys and the public-safety commissioner, asking first for a declaration that the pistols it now sells fall outside the definition, and otherwise for a ruling that the ban is void for vagueness, bans handguns in common use in violation of the Second Amendment, and restricts speech in violation of the First. The same day the National Shooting Sports Foundation, Texas pistol maker Shadow Systems and Wallingford's Blue Trail Range filed a separate Second Amendment suit (NSSF v. Griffin, No. 3:26-cv-01528). Both ask for an order before October 1; Judge Kari A. Dooley set the two injunction motions for a joint hearing on September 29. This summary is drawn from the complaints and docket — no ruling yet. The case parallels The Firing Pin, LLC v. James, the challenge to New York's version of the ban.
