For years I have used a shotgun for hunting all forms of animals from rabbits to deer. But until recently, I never really regarded them as a home defense weapon. Instead I have always relied on my Glock 22 for that task. Most of my shotguns have long barrels, not particularly good for home defense. I've looked at a gun which I believe is a Mossberg Intimidator (or something like that)... basically a 18 inch barrel, pistol grip, heat shield over the barrel and extended magazine. How do these guns rate for self defense? I was wanting something short to keep under the bed. Feel free to give me any advice on this particular gun or other shotguns which fit the same need. Thanks in advance for you replys!
