Well twin,
Although I didnt see it,I have heard from a guy who was attending a gunsmithing school. They were at the range,and a 1911 went full. Surprised by the recoil and suddeness of the situation, the gun kept coming up,then back,till the poor guy actually shot himself in the head. I guess that would be a bad situation.
Short disconnectors are also a problem which can lead to this situation.
Frankly guys, this is a deal that really shouldnt even be discussed in the forums. Ok, OK, my opinion.
If you encounter this,like the others have said,go to a pistolsmith.
I would also suggest popping the slide and barrel off the frame after the gun is cleared,just in case.
