Overview
Built for compact handling, this 20-gauge pump is aimed at hunters and shooters who want a short, easy-to-manage firearm for close-quarters use, home protection, or time at the range. The bird’s-head Raptor grip and ribbed forend with strap are designed to help keep the gun under control, while the ambidextrous safety and twin action bars support straightforward operation. A 14.375" heavy-walled barrel, cylinder bore choke, and drilled-and-tapped receiver round out a practical setup with room for optics if desired. It is a specialized configuration, so buyers should be comfortable with its compact format and check local laws before purchase.

Considerations & Trade-offs
- Compact dimensions make it easier to store and handle, but the shorter 14.375" barrel and Shockwave format are less suited to traditional long-gun use.
- The bird's-head pistol grip and strap-equipped forend are designed for control, yet they create a different handling feel than a conventional shotgun stock.
- Cylinder choke and the listed barrel setup keep the configuration straightforward, but they do not offer the flexibility of interchangeable choke options.
- Local and state laws may restrict sale or possession, so legal status should be verified before purchase.

Frequently Asked Questions
Is the Mossberg 590 Shockwave a shotgun or a firearm under federal law?
The product is described as a 20-gauge pump shotgun, and the long description notes that the ATF has confirmed the 590 Shockwave as a "firearm" under the Gun Control Act, not a Class 3/NFA firearm. Local or state laws may still restrict sale or possession.
What capacity does this model have?
The title lists it as 5+1 rounds.
What type of grip and forend does it use?
It uses a Shockwave Technologies Raptor bird's-head grip and a ribbed forend with a strap to help keep your hand under control.
Can optics be added to this model?
Yes. The receiver is drilled and tapped, so optics can be added to supplement the brass bead.
What action and safety features are listed?
The description lists a pump action with an ambidextrous top-mounted safety, dual extractors, positive steel-to-steel lockup, twin action bars, and a smooth-operating anti-jam elevator.
