I have a Mossberg 500A that I bought 10 years ago. Gun has maybe 500 rounds through it. I like having a good shotgun around, but I prefer to shoot handguns and rifles at the range. I have the itch to buy a new shotgun for some reason (less than $300). Is there a point? Is the Persuader or 590 a better gun, or is the difference minimal? Remember, the gun is mostly a "just in case" gun. Should I go Remington 870?
