It is SAFE

The Department of War Confirms Modular Handgun System (MHS) aka SIG SAUER M17 and M18 is safe and reliable. After some heated arguments from different users and negligent discharges all the guns were ordered for a full scale inspection. SIG SAUER even has a dedicated website for this topic: www.P320Truth.com

Following an incident in July 2025, the Air Force Global Strike Command ordered an evaluation of the M18, which is a carry version of the P320 pistol, while the M17 is a full size. The initial evaluation showed that no weapon discharges were attributable to a malfunction. Global Strike Command reinstated the M18 in August 2025, while DAF completed its inspection, which is summarized in its January 2026 letter.

On August 7, 2026, DoW confirmed the SIG SAUER Modular Handgun System pistols, including the SIG SAUER M17 and M18, are safe and reliable, saying it underwent extensive testing where more than 1.5 million rounds were fired and “all investigated incidents of alleged ‘uncommanded discharges’ have been traced back to the trigger being pulled, and not due to an issue with the firearm.” The full DoW statement is available on the U.S. Army’s Capability Program Executive website.

Following the inspection of 113,479 M18 firearms, DAF said the results “reinforce confidence and assurance that the M18 remains safe and reliable for DAF missions.” DAF’s inspection found “100% of the inspected weapons exhibited no signs of any condition that could have allowed the weapons to experience an ‘uncommanded discharge.’” The full DAF letter dated January 23, 2026, is available at Soldier Systems.
