I own a Benelli M3 Super 90 with a 20” barrel.

I plan to do some duck hunting soon and in lieu of buying a new shotgun, I’m trying to get my hands on a longer barrel.  As I understand it the M3 was shipped with various barrel / sight configurations and they make a 26” field barrel with a bead sight – that is exactly what I’m looking for.

Can anyone in this group point me in the right direction to procure a replacement barrel for my M3?

If not, I’m looking at a Mossberg 935 or Benelli Supernova as a new shotgun for wing hunting – thoughts?

Thanks for your input.
