A major class action lawsuit against Glock, Inc. is currently moving through the courts — and if you own certain Glock pistols in California, you may have already received a court-approved legal notice in the mail.

The case, Johnson v. Glock, Inc., centers on allegations that certain Glock handgun models contain an “unsupported chamber design” (UCD). According to the plaintiffs, this design may increase the risk of casing failure under specific conditions, potentially leading to catastrophic malfunctions. The lawsuit claims Glock has known about the alleged issue for decades and failed to disclose it to consumers.

Importantly, the case does not currently involve a recall, criminal charges, or any admission of wrongdoing. Glock has denied the allegations, maintaining that its pistols are safe, properly designed, and fit for their intended purpose. The company disputes claims that consumers were misled or that the firearms are defective.

At the heart of the lawsuit is an economic argument. Plaintiffs contend that because of the alleged chamber design issue, consumers in California overpaid for their firearms and that the pistols were “devalued” due to undisclosed risks. The case is still in litigation, and no trial date has been set. The plaintiffs must still prove the design is defective, that Glock had a legal duty to disclose additional information, and that buyers suffered measurable economic harm.
