Any of you had problems with this gun having difficulty in opening? I received the gun and was impressed with the fit, finish, and overall quality. I shot around 125 round very quickly in trap doubles. The gun subsequently would not open. After letting it cool for hours it still failed to open. I eventually took the stock off and freed the action. I think the problem is that the extractor is made of an inferior metal and that it bent due to the heat. I called Benelli customer service and they immediately sent a new extractor and told me to send the gun if that did not fix the problem. They stated this is not a common problem. Any experience with these guns?
