I am considering selling my Beretta 391 20 gauge. It has a synthetic stock. I would like to get a fair value price for it of course. I have looked on Gunbroker and have not seen any recent ones sold. Before taking it to any of my local gun shops I would like to have some sort of ballpark amount to expect and so that I don't get screwed. It is in very good shape. Does anyone know what a fair value would be on one? Thanks for any help you could provide.
