ERA Brazil made for F.I.E. Miami FL. 12 gauge coach gun. Light primer strikes.?

Posted about this gun I traded a Maverick 88 in for about a week ago asking if anybody had heard of it. Finally got to take it out to the range today, and the accuracy for this IC Choke on Skeet shocked me. The barrels have to be perfectly welded together, quite impressed.

I was until around the 20th round. The right chamber is having light primer strikes now. I can rotate the shell after it fails to fire and the second strike will usually make it go off, but just trying again zilch.

Is it worth trying to have the shop send it to ERA for repair, it's new when I purchased it but I have no experience with ERA. Anybody have any know how on how ERA or F.I.E. handle repairs? I'm about ready to tear it apart and see what the issue is myself.

If I can tear down a 1851 Colt BP Revolver into all 37 pieces this should be much easier shouldn't it? Never torn into a break open shotgun's mechanism before.
