There's no locking detent on the front of the ejector rod, which is sort of Colt-like. What appears to be a separate brass grip frame made me initially think that the lockwork forked up from below, like in a Charter Arms or Ruger, but flipping it over revealed a conventional sideplate like a Smith or Colt. It's available with both round- and square-butt grip frames.
It's a fairly decent-sized piece for a .357 Magnum. If it's a success, likely other calibers will be along.
I'm going to try to get one to write up for a dead tree outlet.
