It's an experiance and reputation thing. If it were a [color=#FF0000]█[/color][color=#FF0000]█[/color][color=#FF0000]█[/color][color=#FF0000]█[/color] shotgun, word would get around. Well if it's a good shotgun word gets around too.
We own an 870 and a Winnie. I feel that either of those is about equal durability wise. I like the action of the Win better than the 870 though. I like the trigger of the 870 better, I like the way the sidesaddle attaches to the 870 better than the Win. The Win dis/re-assembles easier than the 870.
All new Mossbergs seem nice. All older Mossbergs are loose as a goose so the durability is just not there. Or such has been MY experiance with them.
