I don't think that the pistol comes from an Italian importer. Every single pistol imported in Italy must have the proof marks of the "Banco Nazionale di Prova" of Gardone Val Trompia on barrel, slide and frame (
Banco Nazionale di Prova per le Armi da Fuoco Portatili e per le munizioni commerciali.).
.30 Luger IMHO is a very nice caliber,although less powerfull than 9 Parabellum and actually it was used in Italy and in many countries where 9x19 was not legal as well. At present in Italy they bypass the problem with 9x21. Although reloading .30 luger could be a bit tricky, shooting it is a real pleasure and as a matter of fact, it is amazingly accurate,
