CHEYENNE, Wyo. The United States Air Force has temporarily suspended the use of the SIG Sauer M18 pistol across its installations after the death of a security forces airman in Wyoming. The move, confirmed by the Air Force Global Strike Command, includes immediate safety inspections of all M18 sidearms. The M18 is a variant of the SIG P320, a striker-fired handgun adopted by several branches of the U.S. military. The firearm has faced growing scrutiny due to lawsuits alleging unintentional discharges without trigger activation. SIG Sauer denies these allegations, attributing incidents to user error. Still, multiple law enforcement agenciesnow including the Wyoming Highway Patrolhave ceased issuing the weapon. According to reports, the Wyoming incident involved an unintended discharge. While no official cause has been released, it has prompted renewed debate over the design of striker-fired pistols and the absence of a manual safety in certain configurations. Plaintiff attorneys argue that the M18 should be recalled, citing dozens of injury cases nationwide. The Air Force has not disclosed whether the pistol involved had been upgraded under SIG's voluntary 2017 program. Investigations are ongoing, and service personnel have been instructed to conduct function checks and safety validations.
