SIG Sauer Scores Major Legal Wins in P320 Litigation as More Cases Are Dismissed

On July 16, 2026, the Eighth Circuit Court of Appeals ordered the complete dismissal of a major SIG Sauer P320 class-action lawsuit (Glasscock v. SIG Sauer), ruling that hypothetical product defects and mere ownership are insufficient for claims. This decision builds on a total of roughly 20 recent case dismissals for the manufacturer.
