A report by the FBI’s Ballistic Research Facility that was recently made public has placed the Sig Sauer M18/P320 series of striker-fired semi-auto pistols back into the spotlight. The report was based on the BRF’s tests of a Sig Sauer M18 that had been issued to a motor officer with the Michigan State Police. That pistol experienced an “uncommanded discharge” in July 2024, according to the document. The incident occurred while the gun was holstered, and in front of multiple witnesses. It joins a substantial list of similar reports, many of which have resulted in lawsuits. 

The report was released Monday after a public-records request to the Michigan State Police, the agency confirmed to OL, and distributed Tuesday in a YouTube video. The results of the August 2024 report were inconclusive, but that hasn’t stopped a renewed flow of online speculation by people questioning the pistol’s design. At issue is whether the P320 and its variants are capable of an uncommanded discharge — meaning that the gun can potentially fire when there is no contact with or manipulation of the trigger.
