The Mossberg 590 Shockwave has quickly become a popular firearm choice for home defense and other applications. This in-depth guide explores its features, benefits, drawbacks, and everything you need to know about the 20-gauge variant. We'll cover its performance, legality, and compare it to similar options on the market.
Understanding the Mossberg 590 Shockwave
The Mossberg 590 Shockwave, in 20 gauge, is a short-barreled shotgun designed for close-quarters combat or home defense. Its compact design makes it highly maneuverable, but it sacrifices some of the range and accuracy found in longer-barreled shotguns. The "Shockwave" designation specifically refers to its pistol-grip-only configuration, eliminating the need for a traditional stock. This legally classifies it differently than a traditional shotgun in many jurisdictions.
Key Features of the 20 Gauge Shockwave:
- Compact Design: Its short barrel and pistol grip make it incredibly easy to handle in tight spaces.
- 20 Gauge Versatility: The 20 gauge offers a good balance between power and recoil, making it suitable for many users. It's less punishing than 12 gauge while still delivering sufficient stopping power.
- Reliable Action: The pump-action mechanism is known for its reliability, even under stress. Mossberg's reputation for durability is well-earned.
- Pistol Grip Only: This design is key to its legal classification and usability. No shoulder stock means more maneuverability but potentially less stability.
- Accessory Rail: Many models include a Picatinny rail for mounting accessories like lights or lasers, enhancing versatility.
Performance and Handling
The 20-gauge Shockwave delivers impressive performance in its intended role. The shorter barrel naturally leads to a tighter shot pattern at close range, maximizing effectiveness in home defense situations. However, longer-range accuracy suffers compared to a longer-barreled shotgun.
Recoil and Accuracy:
- Recoil: While less than a 12-gauge, the recoil is still noticeable, especially for those unaccustomed to shotguns. Practice is essential for comfortable and accurate shooting.
- Accuracy: Accuracy is best at close ranges. Expect a wider spread at longer distances due to the short barrel. This is not a long-range firearm.
Ammunition Considerations:
Choosing the right ammunition is crucial. 00 Buckshot is a popular choice for home defense, offering a good balance of stopping power and pattern density. Birdshot is suitable for pest control, but less effective for self-defense. Experimentation with different ammunition types can help determine what works best for you and your shooting style.
Legality and Regulations
The legal status of the Mossberg 590 Shockwave can vary significantly depending on your location. Because it lacks a traditional shoulder stock, it’s often classified differently than a standard shotgun under federal and state laws. It's crucial to research your local and state regulations before purchasing and owning this firearm. Always consult with a legal professional or your local law enforcement agency to ensure compliance. Failure to do so could result in serious legal consequences.
Comparison to Other Short-Barreled Shotguns
The Shockwave competes with other short-barreled shotguns and "firearm stabilizing braces," but its distinct features set it apart. The following table compares it to some competitors (note that specifications may vary between models and manufacturers):
| Feature | Mossberg 590 Shockwave 20 Gauge | Kel-Tec KSG | Other Short-Barreled Shotguns |

Conclusion: Is the Mossberg 590 Shockwave 20 Gauge Right for You?
The Mossberg 590 Shockwave 20 Gauge is a powerful and compact shotgun ideally suited for home defense and close-quarters situations. Its maneuverability and reliability are significant advantages. However, its short barrel impacts long-range accuracy, and recoil can be substantial. Thorough research into local laws, careful consideration of its limitations, and extensive practice are crucial before purchase and use. Remember that responsible gun ownership includes understanding the legal implications and safe handling practices of any firearm.
