I'm looking to buy a dependable 12g shotgun with a barrel at 20" or shorter for a home defense/campsite gun. I don't want to pay more than $450, so I narrowed my search down to two Remington 870's. I believe that they both have "Tactical" in their model name. The issue I'm addressing is the finish on these weapons. One is Power Coat Grey, which I've heard horror stories about flaking off. The other is what they call Blasted Black Oxide. The model numbers are 81202 and 81198 respectively.
Any help is much appreciated
Also I'm open to other weapon systems as well.
