RE: a good shotgun for my wife
You, might want to check out brownings website, they have a semi auto gold designed specifically for women. If she is interested in a 12 ga. semi the Beretta 391, and Browning Gold/Winchester SX2's are very soft in recoil, but you would have to have the stock fitted to her, which probably means a higher comb and a shorter pull at the least. But a properly fitted gun will leave her with much less perceived recoil.
