Bruce Gray (grayguns) is tied to Sig. UMMV.One tester, I believe his name is Gray found 4 actions needed to occur to cause a discharge. That is 4 failures of internal safeties
That is 7 year old news......I also posted this in another related thread: SIG has announced a free upgrade to the 320 trigger system. Details at https://www.sigsauer.com/p320-voluntary-upgrade-program. Looks like it might solve whatever the issue(s) is/are. [Wonder if the DOD is going to take them up on the offer?]
