I have the mod 935 turkey gun, about the only difference I can see is the extended choke is ported instead of the barrel. I bought is about 5 years ago, I see they are listed at $900.00 now, I didn't pay near that much. I have never had a problem with it and it throws a heck of a tight pattern. I never shot 31/2 inch shells through, I use 3 inch.
