I have a fetish for the older Beretta SxS 16ga guns. The 409PB was first made with the cross bolt and later external cross bolt went internal. I'm sure there is a more technical term for this change. I am in the process of trading a 16ga Silver Hawk for a 20ga 410 mdl.Beretta. The 16ga. seems to be priced with the same as the older 20ga Beretta Silver Hawks. I have seen asking prices in the $2000 to $2200. range. They stay listed for a long time at these prices. The ones I see sell are around $1500 to $1800 and in good shape, most with double triggers.I hope you enjoy yours as much as I enjoy mine.
Best,
Ron
