Anyone had any experience with one of these? Got the security model with the 18.5" barrel on sale for $160 and it seems pretty solid. Started thinking about getting the 24" slug barrel but it costs almost as much as the entire shotgun. Thinking about getting another Maverick and having one for hunting and one for defense instead of having to mess with barrel swapping. One thing I can't figure out is if the barrel is rifled or not. Can't find on anyone's website if "rifle" barrel just means it's intended for slugs or actually rifled.
