I think a Browning A-5 has a light recoil as does a Remington 1100, but the lightest recoiling shotgun I have ever shot was about a month ago. I am not familiar with the Berretta model numbers (it was a club members gun) , but it was a Berretta semi auto. I think the model was something like X400 but not really sure. The down side to this gun was I did not like it's 3 shot capacity, (4 if the P.I.T.A.plug was removed) and I did not like the wood - kind of fake looking. It was also expensive (around 1,500 bucks). It is VERY LIGHT in weight and has a recoil shock absorber built into the stock of the gun. I am certainly no expert on this particular shotgun, but for someone who is super recoil sensitive, this one would be worth a look at.
