Not really if you will do a couple simple things. I took some camo duct tape and put it around the sock at the end of the forearm. I also used some around the top of the stock after stretching the sock tight. This helps keep it all tight. After I cut out around the ejection port, I folded some tape around the edges to create a "seam" so it would be smooth. I did the same thing at the loading port. Then I took a neoprene stock shell holder and put around my stock to hold the sock in place. All of this worked pretty good. I'd be using it again this year, but I bought an 835 ultimag. My gun I used last year didn't have 3" or 3.5" capability and like I stated previously, I didn't like getting the dew on the sock and having my gun stay wet for a while. The dew usually dried before the end of the hunt, but rain.........and my grandpa gave me the gun 25yrs ago and it still looks new and I don't take a lot of chances with it.

One other thing worth mentioning, after shooting the gun several times, the sock had holes burned into it at the gas port at the end of my forearm. May just be my model gun, I don't know. A buddy of mine was using an 1100 Rem and didn't have the problem. But he didn't shoot as much as I did either.
