Sig Sauer class action lawsuit overview:
- Who: Plaintiff Patrick Schreiber is suing Sig Sauer.
- Why: Schreiber claims the company’s P320 pistols are defectively designed, making them extraordinarily dangerous.
- Where: The Sig Sauer class action was filed in Washington federal court.
A new class action lawsuit claims Sig Sauer has sold thousands of P320 pistols that are defectively designed and extraordinarily dangerous.
Plaintiff Patrick Schreiber filed the class action complaint against Sig Sauer Inc. on Nov. 17 in a Washington federal court, alleging violations of state consumer laws.
According to the lawsuit, the Sig Sauer P320 pistols have a defect that makes them extraordinarily dangerous compared to similar pistols.
The defect stems from the P320’s design, which lacks external safety features despite being effectively cocked and ready to fire as soon as a round is chambered, Schreiber claims.
This, combined with the pistol’s light and short trigger pull, creates a situation akin to carrying a loaded revolver with the hammer cocked back, the Sig Sauer class action lawsuit says.
Schreiber says Sig Sauer has known about the defect for years but has failed to inform consumers or take steps to address the issue. As a result, P320 users have experienced numerous unintended discharges, leading to serious injuries and prompting some law enforcement agencies to replace their entire inventory of the Sig Sauer P320 pistols, the lawsuit says.
Lawsuit: Sig Sauer P320 pistols lack safety features
The Sig Sauer class action lawsuit claims the P320’s design is unique in the U.S. pistol market, combining a very light, short trigger pull with a design that cocks and energizes the weapon anytime it is loaded.
Despite being fully energized with a short, light trigger pull, the Sig Sauer P320 lacks any external safety features, such as a manual safety, trigger safety, or grip safety, the lawsuit claims.
Sig Sauer’s marketing team decided to remove these safety features during the pistol’s design phase, the class action complaint alleges.
The lawsuit also claims Sig Sauer has collected numerous incident reports concerning the P320, indicating a high risk of accidental discharge. Despite this, the company has allegedly dismissed these reports and videos as “anti-gun” or fraudulent.
The class action lawsuit seeks to represent all consumers who purchased a Sig Sauer P320 pistol without an external thumb safety in Washington state from Nov. 17, 2021, through the present.
The plaintiff is seeking damages for consumers who overpaid for the defective pistols and an injunction requiring Sig Sauer to disclose or repair the defect.
In related news, an identical lawsuit against Sig Sauer was granted class certification in Missouri in July 2025.
