Interesting. In any case (pun intended) WD-40 is the first step. Get the receiver submerged and fill the barrel with it. A gallon paint can is what I use. Autozone here carries WD by the gallon - not aerosol. Check it every few days and keep the barrel full. Also I have had rounds come loose after the WD treatment.
Mind gun safety and barrel discipline. PM me if you want to chat about it after it has soaked for a few weeks.
I have two gallons of WD-40. Just need to get a vessel.
When it first jammed I was beating on the slide with a rubber hammer. I decided to stop as that damn round was going to blow up in my face.
Thanks for taking the time to respond. I will certainly let you know the outcome, as this is a rare event.
