I'm not sure what the weight. I would imagine you could give Perrazi a call and ask them for the spec's on it.
Barrel weights differ from barrel to barrel so calling Perazzi wouldn't be any help. It would be stamped on the bottom barrel on the left side. It will say KG 1.64 or something like that with then the bore diameter like 18.4.
Depending on the weight I might be interested in the gun.
Just as a suggestion. If you are new to this forum. Please consider including as much clear and concise information as possible from the get go. It will save you a lot headaches and you can avoid a lot of the questions you have been hammered on. We all learn this. i know when I did my first posting i got bar b qued like you have about the photos, barrel weight, bore diameter, choke constriction, etc. Just a suggestion not a criticism. Ultimately you want to present your product in the best context to sell. Good luck with your sale and best regards.
