Fratelli Fuf What?
I believe you might be refering to a Tanfoglio T-275?
I don't know much about that model, and am not even sure they have ever been imported into the U.S.
At any rate, EAA the American Tanfoglio importer, doen't still have them if they ever did, and it is unlikely they have parts or accessories either.
Sorry I can't be of more help, but I never heard of a Fratelli Fauf before.
