LFD research has posted a video regarding how the P320 could potentially go off without pulling the triger.
if i understand this video correctly, He claims that one of the source of these issues is cascading and stems from
-a mismatched FCU is installed improperly; i.e, a 10mm being put into a 9mm frame, in a way that doesn't fully engage the striker sear (note that the assembly procedure has changed from 2014-16 era P320s.)
-a failing striker safety
Unless I've missed something, one thing to note is that unlike the previous drop safety issue w/the trigger weight, there is nothing inherent to the design that makes it falliable to UD's, except maybe being able to put a 10mm FCU into a 9mm frame, but If the rumors about sig's shitty QC practices are true, which I personally do believe they are, I think it would be extremely easy for a gun that has all these issues come out of SIG's factories, thus inducing an Uncommanded Discharge like those we've seen on video so far.
R.E: on the MIM'd striker safety, it seems that according to this video, the P320
DID use to have a MIM'd Striker safety, but it seems it has since been replaced with a stamped one in newer designs.

So whats to learn from this? If i already own/If i were to buy a new P320, right now, I would do two things; check the FCU to make sure it isn't a 10mm FCU, and ensure that the striker safety works.
If I was interested in Customizing the gun, I would be EXTREMELY WEARY of swapping out components with other 320's. I know the whole selling point with the P320 is that you can easily change different parts, and it'll "just work", but considering that there have been numerous design changes that will affect the safety of the gun, I think its reasonable to assume that using parts from P320s of a different model year will cause some unintended consequences.
P.S; this dude looks like Karl Kasarda's cousin, look at that hamplanet
