I haven't handled the new gun, but a couple of differences stand out in the photo. Rizzinis, like many Italian guns, have very obvious sleeve seams. Those do not appear on the photo of the CSMC version. The Rizzini also uses a safety barrel selector. Photos don't show the same design on the CSMC. The frame sculpting is also different. Obviously, I haven't seen the actual action mechanism to see whatever differences may exist - but I would guess no one else has either?

CSMC is going into production on this gun, and my impression talking to them was that it was not merely an assembly operation of imported Itallian parts. Assuming it is only functionally a clone, then I assume they have a production licensing agreement with Rizzini?
