DO NOT FIRE IT! I suspect you would not attempt to fire it, but if so it may very well blow up in your face.
I believe the firing pin shouldn’t line up with the shell properly, so nothing should happen.
But yes, if it did, it would be ugly
I imagine this happens from either excessive dry firing or too hot rounds
.
I second that statement! A friend of mine had a Ruger revolver that had the same problem. I was standing next to him and the gun was shaving lead from the bullet when he fired it. I got hit with lead shavings a couple of times. He wisely quit using it and had it fixed by a good gunsmith.
