How did the 'firing pin nail" get out of the gun? Did the pierced primer blow the gun apart?
Questions that I was asking myself. I am having a hard time with the concept, that the bogus pin could make it past the hammer, that there was enough pressure bled off to cause this to happen and that the pressure could be maintained after escaping the primer hole, entering the FP hole and then expanding inside the rear of the slide, blowing out the FP stop....with a bullet going out the other end. Trouble imagining the physics of it all.
