My wife says we need a new home defense gun. I want a shotgun that can do more than just sit under the bed. I was thinking of getting the Remington 870 Express Turkey gun. It's a 12 guage with a 21" barrel, holds 3" shells. It would be great for home defense with some buckshot in it in my opinion and all I have to do is put a turkey choke on it and I'm ready to turkey hunt. What do you think?
