Yeah at least it held together until the chamber pressure had dropped a bit.
All I can say is "WOW".
A marine friend swears he had this happen to someone down the pistol firing line from him with a M9 that was very worn.
Ouch...he's lucky it didn't smack an eye.
Yeah it seemed to flip up.
That said Eyes and Ears!
Now he knows what the left over piece was for. I agree with Ouch.
Wonder what kind of pistol that is...
