Beretta A391 3.5 Xtrema

I own a Beretta Xtrema and noticed that the gray rubber inlays in the stock became sticky and deformed. I contacted Beretta and they advised me to wash with Dawn dish soap. I did this several times and it became worse. I looked it up on the internet and have found that it is a common problem with Beretta stocks. It is referred to as the Beretta sticky stock. I contacted Beretta again and they said they have received several calls regarding this defect and will not rectify their problem. so I'm stuck with a shotgun that is worthless with a defective stock. Browning had a similar problem but replaced their defective stocks. After more research, I have found that Beretta does not stand behind their products. I've talked to several people with the same problem and they were given the same response by Beretta. I just want to let everyone know, buyer beware.
