遇事不決問GPT:
There haven’t been any confirmed accidental discharge cases involving the SIG Sauer M17 or M18 comparable to those seen with the civilian/military P320 variants. Here's a breakdown:
---

1. No documented ADs for M17/M18
A Reddit user on r/SigSauer noted:
> “The M17s and M18’s have not had reports of accidental discharges. Since it's the new standard issued sidearm, if it was going off on its own, we would have heard about it by now.”
Another commented that military users are highly trained and less likely to try to conceal negligent discharges.
That matches the lack of any mainstream news or filed lawsuits involving the M17/M18.

2. Why the M17/M18 are safer
External manual safety: Unlike many civilian P320s, both M17 and M18 include external safeties, an extra layer of protection that prevents the gun from firing unintentionally—particularly during drawing or holstering.
Military-grade controls: The M17/M18 follow military specs, including tighter manufacturing tolerances and quality assurance protocols compared to civilian versions.
Holster & training consistency: Military gear is standardized to match the pistol’s profile and is rigorously qualified, reducing risks from holster-trigger interference or foreign objects in the trigger guard (a contributor to some P320 discharge reports).

3. P320 accidental discharge context
Over 100 reported unintended discharges and at least 80 injuries have been tied to civilian/military P320s, often while holstered or during drop tests .
Investigators pointed to factors like MIM-part wear, poor sear engagement, incompatible holsters, and a lack of a physical safety levers in civilian variants .
High-profile lawsuits (Georgia, Philadelphia, etc.) settled or awarded damages highlighting the issue .

Bottom line
M17/M18 have no documented accidental discharges to date.
This is likely due to a combination of:
External manual safeties
Military-grade holster compatibility
High-standard QC & training protocols
Meanwhile, the civilian P320’s accidental discharge cases stem from its "fully cocked" striker design with lighter trigger pull, lack of mechanical safety, and inconsistent holster or component compatibility.
