None I am aware of after the 1930's, and they were doubles I believe. I wish Browning would be the first, since they teamed up with Winchester and have their own brand of ammo now. How cool would a 3" 16 semi-auto be?They make 3" 16 gauge's? I'd line up for one.
5 lbs 13 oz.With ammo availability for the 16 I wonder if this will be a marketing blunder for Browning? It must be built on a 12ga frame? Why not produce a 20ga first?
