The U.S. Army is not taking any actions regarding its Sig Sauer M17 and M18 pistols based on the findings of a recently disclosed FBI report that has raised new concerns about the design’s ability to fire without the trigger being pulled. Sig has also refuted the results of the FBI’s initial evaluation, which it says the bureau was subsequently unable to reproduce using a mutually agreed-upon testing protocol. The new details from the FBI’s report have already sent a shockwave through the civilian firearms community in the United States, where confidence in P320-series pistols, a family that includes the M17 and M18, is already severely strained.
In August 2024, the Michigan State Police (MSP) requested that the FBI’s Ballistic Research Facility (BRF) evaluate a commercially-sourced version of the M18 pistol that had been involved in an apparent “uncommanded discharge” the month before. The BRF conducted a technical evaluation and produced a report, dated Aug. 30, 2024. The MSP released the report with minor redactions last week in response to a public records request, and a full copy can be found here. The BRF is currently collocated with the U.S. Army’s Redstone Arsenal in Huntsville, Alabama, and is responsible for research, development, testing, and evaluation of small arms, ammunition, and body armor for the bureau, as well as domestic and international partners.
