Doc-of the fired shell casing hits the ejector before the front end of the unfolded case clears the chamber, it's not a 3 1/2 inch barrel..regardless of what's on the side of the thing. Give Browning customer service a call and discribe the problem.. They've been really easy to deal with in my past interactions with them. They bent over backwards when the customer service folks at Winchester totally bummed me out. The shell not clearing the chamber at the point of striking the ejector is all that is required. Call customer service,,they'll likely want the thing back and will replace it.. I clipped the following from the Browning website. I certainly hope this helps!!
