I was aware of the 627-0, but didn't realize there were other models with the same engineering change level. A local gun shop had two 342 Ti revolvers in their used gun case, both priced at $650. One was marked 342 and the other was marked 342-0. I looked them over very closely, and the only thing that looked different was the rifling.
Has anyone else seen a 342-0? Are there other actual -0 models out there?
