First: I have been unhappy with my Benelli. The buttons and levers are illogical as hell, and it doesn't unload from the magazine easily. (Benelli Super Black Eagle II).Benelli
Now, more generally, I would recommend an over and under 20 gauge for dove and quail. They are very light weight, thus easy to carry, and quick to shoulder. Further, the third shot in a semi-auto, if taken, is almost always wasted.
Also, they are so simple in design that they virtually never fail.
More specifically, I would recommend a Beretta.
