Been doing some research on possibly buying another shotgun. I've already got one, a Maverick 88 12G with a 28" barrel but have been deciding on a Mossberg 500 12G 18.5" barrel with a walnut stock and walnut forearm or the Mossberg 590 Shockwave Nightstick also with a walnut grip and forearm but it has a 14" barrel and is like 26" OVL. I think the Mossberg 500 is like $360 or something like that retail price. And the shockwave is a little over $400 which is a little pricey for a pistol style shotgun that doesn't seem to have to many uses. Which one would you choose for like a home defense/truck gun?
