Mostly the TRS but one of them had some kind of return to SIG catastrophic failure that I don’t know the details of. Mostly I get the impression they are not seen as all that durable. Not dangerous just not all that durable.

I'm troubled by all of the problems with this series of pistols as much as anyone. We own one commercial, and I have also built a few more from blank FCU frames, and assembled them. I've been trying to stay on top of all of the issues, and have checked ours every time a safety check is discussed. We had our commercial first purchase upgraded when it was announced several years ago, and all of the ones I've built have been post-upgrade.
I watched a YouTube discussion on the thumb safety on the P320 series, it does only block the trigger. But there have been examples of light striker/sear contacts that have slipped that would not have been stopped just by a trigger block.
I bought another slide end cap and cut the bottom of it off so I could look inside and see the interaction of the sear and the striker. Kinda like the Glock armorer's slide cap.
Some tests show that pushing down on the sear will allow the striker to slam forward, and the movement of the sear downward actually moves the lever next to it that releases the striker block, even without the trigger being pulled. A guy on YouTube with some engineering background showed that cutting the bottom of the sear off to more resemble the sear on the P365 eliminates the movement of the striker release no matter what the other parts do, until the trigger is purposely pulled to the rear. Several other folks have done this and reported the same results.
So, I ordered a few OEM sears and trimmed the sears in each of our P320 pistols, keeping the new ones untouched in case it didn't work. Well, it did work. Now no matter what I do to activate the sear, push it down and release the striker, hit it every which way with a rubber mallet, or manipulate it, it will not fire, until I pull the trigger. With the modified rear slide cap, I can look inside as I manipulate it and see the safety work as it's supposed to.
So, I've had ours apart a dozen times, reassembled a dozen times, and replaced the trigger return spring (the one that extends down from the rear of the FCU) with one with 10% more tension. It increases the trigger pull maybe by 1/2 pound or so, but not really noticeable. But it helps make sure the trigger resets the striker. On all of ours, every time I've reset the striker, there has been 100% contact with the sear. Ive observed it reset 100ish times with each pistol.
So, I'm pretty confident that ours are functioning properly. If someone handed me another P320, I would not be nearly so confident until I examined it.
Mechanical issues always are a possibility. They do happen but with most pistols today they are rare. In the last couple weeks, I've seen two cases of Glocks being fired without pulling the trigger. One had a broken spring on the plunger that blocks the striker. The other had a bunch of after market parts that produced a stacking tolerance issue. While both were quickly discovered, they both happened. That won't stop me from using my Glock or the Poly80 builds using Glock parts. I trust them. I also have high confidence in my P320s.
Those are my opinions and I am sure others have lots of other opinions and that's OK with me.

There’s a point where a properly functioning, loaded firearm, in a proper holster should be considered inert. Otherwise, one couldn’t carry and function in day to day activity.

If I’m climbing a ladder, my holstered gun is aimed at my partners head going up the same ladder behind me. If I go prone with a holstered gun, it’s pointed at everyone behind me.

If I take it off my belt and lay it down horizontally, it’s pointed somewhere in 360 degrees. In my car’s trunk, it may be pointed at the gas tank. Or, at the back seat.

Lots of information, and misinformation out there. I am very confused and am trying to remain conscientious of the safety of others and myself. I may revert back to my P229s for CCW until this quandary is resolved.

Same here. I have started carrying my 320 with an empty chamber, but only when the situation seems that potential threats may begin further away. Like camping. The 229 is quite a bit heavier and has fewer rounds in the magazine, making it less desirable for ccw, but it is the one I feel more comfortable carrying, especially around my grandkids.

What we need is some solid diagnosis of what caused the discharges in specific instances. The pistols' parts need to be accurately measured, with wear, any damage or manufacturing errors noted. Potential user errors identified. So far the unofficial analyses indicate wrong and damaged parts plus user error are needed. A top notch lab needs to do the analysis.

I was a bit uneasy about getting a striker fired ccw pistol but relied on Sig's reputation. I had an XD40 previously but didn't use it for ccw, and the ex got it in the divorce.

I’m questioning that part of the story, not the airman or his gun handling skills. I don’t believe everything I read on the internet and that part of the story sets my BS meter off.

However, based on the responses, our military personnel place their loaded guns on their desks pointed at their chests all the time as it is completely unavoidable and that part of the story is therefore unquestionably true.
