I completely understand not wanting to take the Citori to the duck blind. I do bird hunt and shoot clays with my Beretta O/U but take my Benelli auto when water and mud are involved.

As far as 2 3/4" ammo, I personally prefer 3", but I have shot quite a few boxes of 2 3/4 over the years with acceptable results. Unless you just want to buy a new gun, I would use the 1100.
