First time asking a question so I hope I’m clear on the help I need. I’m in the market for a Beretta silver pigeon SP1 12 ***** for sporting clays. Does the current model supposed to have a mid bead. HP Optima chokes and a vented mid-rib? All the advertisements show a picture of a gun with no mid bead or a vented mid-rib. Thanks if anyone can shine some light on this difference.
