So I've been looking around for a cheaper tactical shot gun for a while. Saw a Rock Island Armory shotgun for around $200 and a Remington 870 for around $350 and a Mossberg 500 for around $450. I would prefer to spend around $300-$400 at the most but budget isn't that big of an issue. I'm not sure if I'd be doing a disservice to myself by buying really cheap or if I should spend the extra money for the name brand factor. Let me know what your opinions are, any feedback would be appreciated. Also, this shotgun will be used mostly for home defense. I don't bird hunt or anything like that so I wouldn't use it all that often. Thanks ahead of time!
