I am starting to do some research on shotguns to decide what will fit my needs. My primary purpose is for home defense but I want to be able to upgrade with a lot of accessories down the road. So far I am liking the Mossberg 500 and 590 but was wondering if I should broaden my criteria. I'm basically just wanting a shoter barrel with a pistol grip and stock, something intimidating but also something my wife could use. Any help is appreciated. (I'm also trying to meet my 50 post limit)
