Instead of the Benelli Nova, someone at the Scottsdale Gun Club mentioned that since I have two Remington 870s already, why not go to Cabela's or Sportsmans Warehouse or Bass Pro Shops for a hunting barrel? There were also a couple of aftermarket front sight options that could match the height of my rear sights. I was a bit irritated with myself for not having thought of that.
Well, after a fruitless trip around town to inquire at those places, I went back and lamented that I should have planned ahead since everyone was out of stock or didn't have exactly what I needed. One of the managers mentioned they had a used Wingmaster with an extra barrel that wasn't on display but on their Gunbroker for 250, which wasn't more than what I would have paid for a new barrel and front sight replacement. I ended up going with that.
