"You should have included a warning to the OP: The Star Super in 9X23 is chambered for 9X23 Largo, NOT the more powerful 9X23 Winchester!!!
I just checked their SN add on line, and it is even more confusing. It says on the top of the add for the super B Star 9X19. then further down in the details it says 38 super performance. Below the Star add is another add for the 9MM Largo ammo. WHAT ARE THEY ACTUALLY SELLING??? "
The Star Modelo Suber "B" is in 9mm para (Luger) Tne original Star Modelo Super "A" is in 9mmx23 or 9mm Largo. The 9mm X 23 Winchester is exactly the same external dimension as the Largo, but the cases are thicker and thus they have less capacity and when loaded reach much higher pressures than the largo round. Sarco sells both models. You have to specify which you want. Check the item numbers in the ad. They are different for the two guns. In fact they are different for the Modello Super B C&R and the FFL transfer Modelo Super B as well. Or you can do what some in Europe do and cut a 4mm piece of 9mm casing and superglue it into the front end of the chamber of the Modelo Super A and then shoot 9mm Lugar in it.
