I agree with carver. Also; $1,800 is NOT a lot of money for a good o/u or s x s shotgun. Finally; if she wants a 28 gauge, it's perfectly fine for upland birds and you have already said you have 12 gauge guns for ducks. I don't use my upland guns for ducks either. I've killed LOTS of upland birds with a 28 gauge 870, including wild pheasants.
