Quick update! Something must have loosened up in the night. It now works perfectly again.

Now that my barrels hook and unhook, I took the gun out today and it performed well. Brought home a limit of wild pheasants. I then unhooked the barrels, cleaned them and they are ready for the next time I need to get some free-range, organic fowl for a great meal. Cheers, Jack

PS - they were taken with hand loads gratis of Rich Anderson from a couple years back. Nice loads Rich. Thanks.
