All purpose choice you say... probably a 12 guage with a combo barrel for shot and slug, and this will suffice for hunting needs. At least this way you don't have to switch back N-forth and shell out for the extra barrels. And as far as Home defense goes...just let someone get in front of it just once for the wrong purpose..and you will see how effective any shotgun will be.
Remember that 'New' doesn't constitute better, and something under $400 bucs doesn't mean incapable.
