After contemplating your problem for a while, it sounds like the pin that holds the lever to the bolt may have backed out enough to jam it up. Any good smith should be able to fix that, but in my experiances, I have met a few that thought they knew the '92s, but ended up that I knew more than they did.
Sounds like a trip to Nate Kiowa Jones is in order. I would recommend that anyway. He is the "MAN" when it comes to the '92s.
