Shotgun powerhouse Mossberg is apparently tired of people having to mod their 12 gauges to run mini-shells, so they now have the heavy-walled 590S series that eats them right out of the box.
The all-new 590S Series cycles 1.75-inch minis, 2.75-inch standard, or 3-inch magnum shells in any combination the user desires due to a redesigned anti-jam elevator and bolt slide combined with the addition of an energy-absorbing bumper. Repeat: these guns don't require the user to install some oddball adaptor to run those increasingly popular mini shells.
The 590S can be stoked with all three common 12-gauge shell lengths, in assorted combinations, with a 20-inch barreled version holding as many as 13 mini-shells. (Photo: Mossberg)
Mossberg has four variants of the 590S, including two traditional shotguns and two compact bird’s head-gripped Shockwave "firearm" versions.
The 590S shotguns include a $708 variant with a Ghost Ring sight, 20-inch Accu-choke barrel and M-LOK forend, as well as a more featureless model with an 18.5-inch Cylinder bore barrel with a bead sight and corncob forend that runs $605. (Photo: Mossberg)
Shockwave models include one with a 14.375-inch barrel and 4+1/5+1/8+1 capacity and one with a longer 18.5-inch barrel and corresponding mag tube with a 4+1/6+1/9+1 capacity. Both are cylinder bore with a front bead and run $605. (Photo: Mossberg)
