Potential Fix for the Sig P320 Failure Mode(s)?

I don’t think so. As I understand the failure mode, the FCU (fire control unit) is allowing the striker to go forward without rotation of the sear. This modification will not fix that problem. Not, by the way, that’s the only problem with the Sig P320.
I have yet to see a complete, full, uncompromised and unbiased FMEA of the Sig P320.

The SIG P320 saga continues!
A SIG engineer filed a patent to fix the "unsafe" P320 in May. It seems they knew.

I’m sure this guy is trying to tell us something, maybe when he learns to put together a useful video he can try again.
Why is itso hard to do a simple, informative online video ?

never really trusted striker fired guns myself. the firing pin is always cocked and ready to go. and there is a reason why a lot of ‘PRO’s ” never chamber a round until they ready to shoot too. and it a plastic gun. I don’t like those either. then again, I am a old fart who likes
steel and wood on my weapons. and a hammer I can see and cock myself.
I have a few Sig Sauer pistols myself. but all of mine have a hammer and made in West Germany on the slide too. a lot of people swear by Glocks too. I don’t like them myself.
they don’t feel right to me.
