Mossberg 590S Shockwave 12 Gauge 18.50" 10+1 3" Pump Shotgun - Full Size Frame

The Mossberg 590S Shockwave Full Size Frame is a tactical pump-action shotgun built on Mossberg's 590 platform and trimmed with the compact Shockwave layout. Chambered in 12 Gauge with a 3" chamber, this model feeds through Mossberg's traditional magazine tube for a 10+1-round total capacity.

An 18.50" matte blued steel barrel is paired with a black anodized stainless steel receiver, combining corrosion-resistant stainless construction with a low-glare tactical finish. Sighting is handled by a clean bead front sight, with a fixed cylinder choke for fast, open-bore shot spread at close range. The pump action is set up for reliable cycling under defensive and range conditions, and the design runs short and light for easy handling.

The defining feature of the Shockwave is the Raptor Birdshead grip in place of a traditional shoulder stock. This pistol-style configuration places the shooter's dominant hand high and close to the bore axis for improved recoil management and rapid target transitions. At 30.75" overall length and 5.50 lbs, the 590S Shockwave is well balanced for home defense, vehicle use, or range work. Right-hand configuration, shipped factory-new from Mossberg.
