Migliaccio & Rathod LLP is investigating reports of a dangerous defect in Sig Sauer P320 and M18 pistols. Multiple user reports indicate that these firearms may fire without trigger contact, posing a severe risk of injury or death. Following the July 21 death of an Air Force Security Forces airman, the Air Force grounded every M18 sidearm for inspection. On Reddit’s r/AirForce, numerous users have shared alarming accounts of holstered pistols discharging unexpectedly, photos of fractured striker housings, and frustrations over repair delays.
Widespread Safety Concerns Over Sig Sauer P320/M18 Pistols
Despite being marketed as “drop safe” and reliable, P320 and M18 pistols have generated at least 100 prior reports of “drop-fire” or “holster-fire” incidents across law enforcement and civilian users. Recent 2025 reports suggest the defect persists even in models that underwent Sig Sauer’s voluntary 2018 “upgrade program.”
Common Problems Reported by Consumers:
-
Pistols firing while holstered without trigger contact
-
Fractured striker housings and firing-control failures
-
Difficulty obtaining timely repairs or documentation
