Curiosity has really gotten the better of me regarding this situation, so I checked the left guide on each of my two 92s. On my Browning B-92, which is .44 magnum, the inner face of the guide is flush like Ranch Dog's. However, on my Rossi R-92, which is .38/.357, there's a "bump" (lump, hump) similar to yours.
Mine doesn't have a bright spot indicating contact with the bolt. If I were in this situation, though, I'd make haste very slowly. First, I'd have to absolutely convince myself the "bump" is the problem. If I were convinced, I'd slowly work the surface and monitor its contact with the bolt. Just filing it flush with the inner surface of the guide might introduce another headache that would be compounded trying to get a replacement guide from Braz-Tech.
Just had another thought . . . Can you see where the bump on the guide is contacting/rubbing/catching the side of the bolt? Is there a chance there's a spot on the bolt that was never milled truly flat or smooth? Touching up that spot might be a little less risky. But, as I said before, I'm just speculating which leaves me feeling a little guilty.
