I have two Star Modelo B’s in 9x19. Very nice pistols to shoot. 1911-ish without the grip safety, but scaled down slightly instead of simply converting the 1911 to a 9x19.
I had a Modelo A in 9x23 Largo, but sold it because of the ammo issue. Handloading 9x23 Winchester cases to Largo pressures was the only realistic option.
Its too bad that the 9x23 Winchester never caught on. It is essentially a rimless .357 (in ballistics, not case length).
