Just a thought, not a slam on either shot gun or manufacturer, but it might be a good idea to get a shotgun that operates the same as your primary rifle (The one(s) you shoot the most). I'm generaly a semi Auto rifle shooter, I don't know how many times at the range I have tried a second shot with a friends rifle and had nothing happen as I forgot to work the bolt

It's funny, and leads to razzing at the range, but in a life or death situation at 0 dark thirty that sort of confusion can get you killed. As I said, just a thought.
Some one once said, "The two loudest sounds in the world are a BANG when you expect a click, and a click when you expect a BANG."
