Wolf, you'll love your new 870 i'm sure. I'm not much for defensive type shotguns, but i hunt waterfowl with an 870 supermag. I also have a Mossberg rifled slug barrel for it and it is right on with sabotted slugs. I don't deer hunt with it any more as i have bought a Savage 210 rifled bolt-action slug gun thats topped with a 2-7 Nikkon. It is the proverbial tack driver. I killed a little scrub buck with it on the last day of the season. 90 yards, took the top 1 1/2 of his heart out! View attachment 156 Notice where the exit hole is.
