Court Dismisses P320 Case in Massachusetts After Years of Litigation Against SIG SAUER

Dismissal of the P320 Case in Massachusetts

In a significant legal development, SIG SAUER has scored a major victory with the dismissal of a federal case concerning its P320 handgun. The United States District Court for the District of Massachusetts ruled on May 28, 2026, dismissing the case of Ahern v. Sig Sauer Inc. after years of litigation. This marks an important milestone for SIG SAUER, reinforcing the integrity and safety of its popular firearm model, the P320.

Overview of the Case

The plaintiff, Thomas Ahern, had initially filed claims suggesting that the P320, which was issued to him by the Cambridge Police Department, discharged unexpectedly without pulling the trigger. This incident reportedly occurred on May 19, 2019, while Ahern was in an enclosed space surrounded by colleagues. However, extensive investigations carried out by both the Cambridge Police Department and the Boston Police Department’s Firearms Analysis Unit concluded that the discharge resulted from Ahern’s mishandling of the weapon rather than any defect in the P320 itself.

According to their findings, the firearm could not discharge without a deliberate trigger pull. This conclusion was supported by rigorous testing, including evaluations by independent third-party experts. In light of this, Ahern voluntarily withdrew his claims just before the trial was set to commence, leading to the court's dismissal of the case with prejudice, meaning it cannot be brought to trial again.

SIG SAUER's Statement

Aloke Chakravarty, legal counsel for SIG SAUER, hailed this verdict as a significant affirmation of the P320's safety standards and functionality. He emphasized that this dismissal adds to a string of nearly twenty similar cases dismissals which reinforce the company's commitment to defending the reliability of its flagship product. Chakravarty also noted that the P320 has undergone extensive testing, proving its robustness and effectiveness, especially in demanding conditions such as military and law enforcement scenarios.

Safety and Reliability of the P320

The P320 is distinguished as a striker-fired pistol and has garnered recognition not only from the U.S. military but also from numerous countries, including Canada, Switzerland, and Australia. Its reputation as one of the most reliable handguns is supported by rigorous evaluations conducted by military testing and evaluations from elite law enforcement groups worldwide. SIG SAUER has maintained that the P320 will only discharge when the trigger is intentionally pulled, a safety feature that has been validated repeatedly through controlled testing and investigations, including those led by the Boston Police Department.

With this latest dismissal in Massachusetts following a similar case in Colorado, SIG SAUER continues to demonstrate its commitment to producing firearms that adhere to the highest standards of safety and reliability.

The dismissal of the P320 case in Massachusetts serves to clear the air surrounding the firearm's perceived defects.
