Mossberg 590S Shockwave 12 Gauge 14.375" Barrel 8+1 Capacity

The Mossberg 590S Shockwave transforms the traditional shotgun platform into a compact, versatile firearm ideal for close-quarters applications and tactical scenarios. This 12-gauge configuration delivers exceptional stopping power while maintaining maneuverability in confined spaces.

What Makes This Different

The 590S designation indicates Mossberg's enhanced shell capacity system, accepting everything from 1.75-inch mini shells to full 3-inch magnum loads in the same magazine tube. Unlike standard shotguns limited to one shell length, this platform adapts to ammunition availability and mission requirements. The 14.375-inch barrel length provides optimal balance between velocity retention and compact handling.

Key Features

• Multi-shell capability: 8+1 capacity with 1.75" shells, 5+1 with 2.75" shells, 4+1 with 3" shells
• 3-inch chamber handles full range of 12-gauge ammunition from mini shells to magnum loads
• Dual extractors ensure reliable ejection across all shell lengths and types
• Raptor birdshead grip stock provides secure control and reduces felt recoil
• Corncob forend with retention strap offers positive grip surface and secure carry
• Matte blued finish resists corrosion and reduces glare
• 26.37-inch overall length meets federal firearm regulations

Field performance demonstrates reliable cycling across the full spectrum of 12-gauge ammunition weights and lengths. The dual extractor system eliminates feeding issues common with variable-length shells in traditional magazines. Law enforcement agencies appreciate the platform's adaptability for breaching, less-lethal deployment, and standard buckshot applications. The compact profile excels in vehicle storage and confined tactical environments.
