So, is your claim that an object in the holster is pulling the trigger causing the discharge? Congratulations, that's SIG's argument and if it was true it would exonerate them.
That’s not my claim. I don’t really trust Sig’s ass-covering on the numerous reported issues.
But in the case of the demonstration in the Wyoming Gun Project video, it is literally the case that an object is being jammed into the trigger until all internal safeties are disabled, then flex and sympathetic movement is applied until the gun goes off.
There may exist a more damning explanation of what has caused the reported uncommanded discharges but that video isn’t it
