I've handled a B Rizzini in a shop, Mcloys in Ireland. He had a wall full of them, and the one I picked up was a sixteen bore. It felt very nice, shouldered nicely, balanced well, nicely figured wood, and felt mechanically of good quality.
But, pretty guns invariably feel nice in the shop. I have learned, to my expense, that the words of wisdom told to me many years ago are true, "There's no substitute for just putting thousands of cartridges through your gun to know it and shoot it". Obviously, if it doesn't fit, have it fitted. Then you proceed t shoot it and shoot it until you know what you and it do together.
