I don't mean to sound like a fanatic., but the Beretta 391 is hands-down the winner as far as quality and reliabilty. It isn't even close.
Go to the clays tournaments and look at what the large majority of shooters (particularly the pros) are using. They are the Beretta autos. You might also want to go on the internet and look up articles on reliabilty of autos, and you will find that the Beretta is overwhelming favored.
I have fired as many as two cases of shells through my Beretta without cleaning it, and it has never jammed, . . . not once. This is not at all unusual, and other Beretta owners will tell you the same thing. If you research the articles, you may find a test that was performed, where 1,000 shells were fired through a Beretta 391 without any cleaning. Again, no jams, . . not once.
Just my experience and opinions.
Best Regards, Big Paulie
