I bought a Benelli Nova Tactical. If I had it to do again, it would be the Mossberg 500.
the reason is that I wanted to swap out to a pistol grip stock at some point. With the Remington 870 or Mossberg 500, this is easy. not so much for the Benelli.
It's neat looking, and dead on reliable, but since I never got to have the pistol grip dealio pan out, I still feel like I went the wrong way...
But anyway, my Benelli shoots good.
