Welcome to the forum fill-up.

To be honest with you I've never heard of a Fausti.Not knowing anything about it I would steer away from it.Are parts available for it?. Who imports it?I'm sure it a cheaply made shotgun.You didn't say what it is. A pump,semi auto, single shot O/U or SxS?I would say you'd be better off buying a shotgun that has been proven and not some off the wall brand.
That's just my opinion and you can take it for that......
Ruger Redhawk
