I originally purchased this shotgun about a year ago with the kick-off option on the butt of the stock. Problem #1 developed when I began to pattern the gun before turkey season. The kick-off was causing the gun to move backward a good 1/2" everytime I shot it. (This was much more notable with 3 1/2" ammo.) This motion was chipping away at my cheek bone (anchor point) which made shooting a lot less fun.
Problem #2 was noted a short while later. The aluminum action was begining to chip away at the point of the rail when the hulls were being ejected. This resulted after approximately 300 rounds.
I returned the gun to Cabelas in June. A month later Beretta replaced the gun with a new model a-400. Minus the optional kick-off. As a result the new gun was much improved in the felt recoil department. No more beatings to the 'ol cheekbone. All of my shotgun problems were now solved, life was great or so I thought.
Problem #3. After cycling around 400 rounds the new gun was working perfectly. It would handle anything I fed it. Until a recent pheasant hunt. Suddenly and quite unexpectantly, while attempting to shoot a late season Colorado rooster, the gun failed for the first time. The action failed to close. After a good deal of frustration, two disassemblies in the field and a few choice words about Beretta autoloaders; I discovered the problem. The spring-loaded magazine cleaning mechanism failed. There was one end of the washer stuck and I do mean stuck! Around the self cleaning plug. (And yes I do clean my guns!) This caused the gun to be unusable. Fortunately a good friend loaned me a "real" gun; a Beretta onyx over/under to complete my hunt.
I've recently returned the gun to Cabela's, which will probably be shipped to Italy for inspection and repair. I hope to be able to talk them into a trade for an over/under. A Perennia would be nice upgrade, but its a bit out of my price range. I do however have a Silver Pigeon 20 ga. which I thoroughly enjoy.
