Gentlemen...lots of great suggestions, thanks so much!
btdst - Would your wife be willing to part with the Micro Citori?
Dave in Maine...yes, I already saw the 20 Ga Flues. She's never shot a sxs, but it might be worth a try. I also saw the pair of guns you mention that Kirby H. has for sale. The Sauer looks great except for the excessive drop (3" at 13 LOP!)
As for double triggers...my concern is that might be a problem for her small hands.
She is not at all recoil sensitive, by the way. She's a dog musher from Alaska.
Ian - those Rizzinis look nice. I didn't see prices on them.

Thanks again!
