One of my BIL and SIL lives in Argentina. I have been there numerous times to visit and usually try to include a hunt. About all I see on the dove hunts are Benelli and Beretta autos. Most shooters dont want the excessive pounding an O/U or SxS gives after 500-1000 rounds in a day.
The extremes of shotgunning arent the reality for most. One one extreme you have the gun club crowd that thinks everyone should want and have a high end shotgun. They are absolutely necessary to find happiness in the field and on the range.
.The other is the tacticool crowd. They see potential danger everywhere and need a high capacity combat shotgun at the ready to defend life and limb.
Reality is most people are in the middle, and happy with midline guns that can serve multiple purposes.
