Yes. A goose gun will have a very long barrel-- something like 30 inches. I have even seen them as bolt actions. Shotguns usually come as pump-actions or automatics. Prices go from around $400 to many thousands. It's not uncommon for a beautifully-made English double-barrel to cost $250,000; I have seen them at gun shows. Hunting shotguns are usually plugged to hold no more than three rounds. A self-defense shotgun can have an extended magazine that will hold at least six, and as many as nine. Shotguns come in wood or synthetic stocks.So I'm trying to buy a shotgun. I am interested in going hunting. I also want this shotgun for self defense. Is there any difference between hunting guns and regular guns?
