I own both an 870 express and wingmaster. After the post about the wavy barrel of the express I just had to check. I have no idea what you are talking about. I guess I have a great express or a lousey wingmaster for I really can't see the difference that you posted. I would say that the wingmaster has a nicer wood finish (more defined grain pattern)but then again I like the satin finish of the express also. Both shoot equally well and both have 28 in barrels. I use them as goose guns and have harvested many birds with each of them.
