I've wanted a 12 ga semi-auto shotgun for a LOOOOOOOOOOOng time. I've got a really nice old WesternField pump 16 ga that dad probably bought back in the late 60's or early 70's from Montgomery Wards but I've decided it's time to purchase my 12 ga. I've really fallen for the Berretta A400 Extreme Max 4 KO that fires all 3 shell sizes. Problem is $1800 is a lot of money for something that I don't use that often. So, what else is out there that is Semi-Auto and will fire all shell sizes? Any suggestions from you guys who know shotguns better than myself is greatly appreciated.
