Had a A303 12 ga. for a while. Loved it, but I'm a lefty and the beretta rep said I would not be able to reverse the safety. For some reason I could not adapt at the time. Sold it for what I had in it. Beautiful gun, shot like a sewing machine. The cycling was the smoothest, fastest I've ever had. It did require, as many gas operated guns do, slightly heavier loads to cycle the lighter stuff. I tried to shoot at least 1-1/8 ounce shells to meet the pressure for the 12 ga to function flawlessly. The shells were a little more but I had better results on dove. Great shotgun for wingshooting.
