However, a local pawn shop as a Remington 1100 for $400 (I don't know how old) but he stated 2 3/4. So IDK if that means it's only 2 3/4.
I wouldn't buy anything with wood if it is going into the field. My advice would be to use the pump for now and then find a 930 duck commander in a year-end sale. You'll be happier with it and there all kinds of after market parts for them.
I fired a 3" load in a 12ga one time. That will never happen again!
