Regular 92FS has black finish, not sure which type; inox has a stainless steel slide and is the best looking gun in the world. The M9 has a straight dust cover and M9A1 has a rail, I personal think they are look cool except the M9A1. There won't be much in difference between made in the State or Italy, I had a M9 and sold it after I saw an Italian made 92 inox.
