It theoretically cannot fail, therefore it has never failed. Despite all of the footage showing the gun going off without input.

"Why don't people know how it's happening/Why can't it be replicated?"
The fire control group, the drivetrain if you will, is wholly unlike anything on the market. It's alien. Current diagnostics rely on systems similar to the old Browning designs or much simpler firing pin blocks.
The gun is not translucent. Nobody can see through all the parts to witness that everything fits together perfectly or not, people have shown pictures of inconsistent wear patterns and broken springs and chipped/rolled-over edges though so clearly something is wrong.
Armorers trained to work on the P320 don't know how it fails so they can't diagnose it. Everyone is learning about the gun in real time because it just got shat into existence 11 years ago to little or no fanfare and spread into every holster like fucking dandelion seeds.
This man is gay.
