Yes, IF.....
All 1100 bbls are interchangeable but if that 1100's set up for 3" shells, it should work OK.
If it's a 2 3/4" receiver, putting a 3" chambered bbl on it will NOT make it work with 3" shells, and good steel 2 3/4" waterfowl loads are non existent.
Look on the receiver. If it says Magnum on it, a new 3" bbl will work....
