Hey, quick question for many of you. I've decided to purchase a 12 gauge shotgun for self-defense in the home. Recently, our neighbors dog was actually shot (Dachsund, by a .22) and then thrown over our fence to try and make it look like our dogs had mauled it. It's occurred to me that I'm not comfortable with the situation so I am purchasing a firearm. While that story was unnecessary for the question I'm still pretty rocked by the fact someone would kill a dog for no reason.

A few questions. I'm looking at a REMINGTON 870. The gun will occasionally see target practice but will generally be for at-home defense (bird/buck shot). From what I've read it seems like a solid choice, I was just looking for opinions.

Also, I've noticed prices differ greatly. I've seen things like 'express super magnum,' 'marine magnum, 'tactical,' 'express self-defense'. The Express Self-defense is the cheapest so tell me to get that one! Also, buying online. Why is it so much cheaper and is it worth buying online or should I stick to a store/show.
