I've used the 870 express exclusively for 20+ years as my main waterfowl and turkey shotgun. It has the 28" barrel and I wouldn't change a thing about it. The longer barrel is a tremendous asset when swinging on waterfowl and I don't find it to be a hinderance while turkey hunting. In other words, the benefit of the longer barrel for waterfowl greatly outweighs any inconvenience while turkey hunting.

Another thing - I don't set down to call in the middle of a viney thicket, so that 28" barrel is rarely anissuefor me.
