And we don't actually know any real details on the airman incident. Mostly speculation. What it seems we've been told was that he set the pistol down pointing at his chest....???
That in and of itself is strange. I assume most people are like me and can count the number of times they've done that on zero hands. Not sure what to think of it.
I'm not dismissing the incidents. As I stated earlier, there does seem to be something strange with 320s compared to other pistols, but it's still not clear what exactly it is. I have a hunch a heavier trigger return spring and a trigger safety might solve it.
