I acknowledge, the various requests for information, as it becomes available I'll add it to the thread.

But you can ask

That will help to figure out what caused the weapon to fire

Your assumption that I have not would be the issue

The gentlemen in question is out of bed and near a working computer only on occasion, between medication and pain, I cannot blame him.

This entire thread is my curiosity, not his.. So info will come when it does

So, another bit of info.
Primer was struck, "looked like a normal hit"
Gun (model still unknown) has not been altered, has been maintained, and the owner stated without any hint from me " Slam fire is normally a firing pin issue, dirty or otherwise, people oil them or don't clean and cause problems" IOW he understands you don't oil that part of the gun and the firing pin /recesses is part of maintenance.

He was at the docs today, so really out of it..... More to follow when i get it.

Thanks to all that have contributed.

There's also scenario C:
The firing pin block pin got gunky, the spring that's supposed to reset it wasn't strong enough at first so the gun legitimately slam-fired, but the shock of the gun going off jarred it lose preventing continued slam-firing. (Don't laugh too hard -- the manual specifically tells you to make sure this part is working correctly as part of the cleaning procedure.)

Ok but keep in mind that:

A. It would have had to lock forward on the last firing of the last round shot out of the handgun. Any other round loaded would have either slam fired or shoved the firing pin back into the slide.

B. The primer wound not have a strike that "looked like a normal hit". It would be teardrop shaped indention from the pin driving into it as it was seating up and into place and then driving backwards and down as it exited.

A primer strike that looks like a normal hit diminishes the probability of a slam-firing even further.

Not the firing pin itself, the firing pin blocking pin -- the part that prevents the firing pin from moving forwards without the trigger being pulled. If the blocking pin gets gunked up, a weak firing pin spring might not be able to prevent slam-fires.
