It's indeed for bird hunting. And pumps are far superior for that because you can have a total of three at that point, as well as a much less expensive gun. Only disadvantage is a single choke, but I get the idea few people really understand how those work anyway.
I would be more concerned with getting a follow-up shot if you fuck up the first one. Most double-barrels are quicker to follow up with than a pump-action. And if you can't get even one clean hit on a bird that's flying away with two shots, you really don't deserve a third. :V
