I'm really not buying the whole "gun just blew up" (see previously posted Ben Stoeger video) stuff regarding the P320.
We literally just dealt with a completely stock Glock Gen3 G19 having a bulged barrel about a month ago due to bad factory ammo (string of fire...squib load followed by normal round...blew the squib out the muzzle along with the normal round...slightly bulged barrel causing gun to malfunction...shooter only realized something was wrong because the slide was locking back on its own).
I'm sure if the gun had been a P320 there would have been more weeping and gnashing of teeth and blaming the gun. The cold hard fact is that with the ammo shortage of 2020 and subsequent increased strain on the supply system there has been a fall off in quality control.
The P320 has become an easy gun to pick-on lately thanks to the legal and media attention.
