I love my .410! I would like to have a 20 inch vent rib barrel for it, making it the perfect length.
Right now it's sporting the 20 inch factory slug barrel with rifle sights. I wish Mossberg would make a 590A1 version in .410, I missed out on the Shockwave.
I had a hard time finding the 18.5 inch barrel for my .410, but keep looking, they do turn up.

Also, try finding one of these-
20” Smooth Bore Deer Barrel with Fiber Optic Sights
I prefer the 12 gauge 20 inch vent rib barrel for its shorter handier length. With the screw in modified choke, it pretty much covers every situation. I wish Mossberg offered a 20 inch VR in .410 not just the 18 inch riot barrel.
Had a chance to handle the new .410 Shockwave, what a great little shotgun! Perfect for the truck, house, or just for fun! Easy for a lady to handle too! Get some of the Super-X loads for it, the stacked 000 buck loads are the best!
