I am looking to purchase a duck/dove gun that can also be outfitted for 3 gun in the off season. I like the Affinity by Franchi, it uses the same technology as the Benelli M2, and is owned by Benelli. I have found extended mag tubes for it, but no after market barrels shorter than 26". The Affinity is only $700 and the reviews seem to be great. I got to look at one at a local store and it seemed to be a quality gun. What do you think?
