Following a fatality of a Security Forces Airman on 20 July, 2025, Gen Thomas Bussiere, the Commanding General of Air Force Global Strike Command has ordered a pause in use of the M18 Modular Handgun pending completion of Air Force Office of Special Investigations and Safety investigations.
In lieu of the sidearm, subordinate Wing Commanders will arm personnel with the M4 rifle in place of the M18. The M18 is manufactured by SIG SAUER and is based on the commercial P320.
While the Internet is rife with rumors, other than the fact that a Security Forces Airman (and by that the AF means a member of the service and not a rank) tragically lost their life in an incident involving an M18, we don’t know much more.
We’re not going to expect official findings for some time. The last fatality in that Squadron was in September 2023 and involved a roll over of an uparmoured HMMWV in inclement conditions and the report was released just last week.
While it would seem at its surface that the pause in use is significant, it has always been Air Force policy to pause training and operational use of systems which are involved in fatalities. This usually includes aircraft or hazardous activities such as diving or parachuting. During the pause, the command’s Combat Arms personnel, who conduct weapons training and maintenance, will wisely conduct 100% inspections of all Wing-assigned M18 weapons systems using:
Technical Order 11W-3-4-32 and additional supplemental inspection guidance in development by AFGSC/A3S. This latter guidance will be interesting to see.
So far, this stand-down is not Air Force-wide and only applies to the units involved in the nuclear enterprise. Aside from collaboration with the Air Force Security Forces Center, there are indications that other Major Commands within the Air Force are also considering a pause in the weapon’s use. This isn’t surprising as they seek guidance at the service level.
We have not yet reached out to the Small Arms program office of the Air Force or PEO Soldier’s Product Manager Soldier Weapons for comment due to this story breaking late yesterday afternoon. Manufacturer SIG provided us with this statement:
“Our hearts are with the service members and families impacted by the recent reported event at the F.E. Warren Air Force Base. We have offered assistance to the U.S. Military as they investigate the incident and remain willing to help in furtherance of their ongoing investigation.”
Below is a copy of the implementing AFGSC memorandum.
As soon as we know more, we’ll share it.
