Frequently Asked Questions
Mossberg 590S Shockwave for sale
How much does a Mossberg Shockwave 590s cost?
Mossberg 590S Shockwave shotguns typically cost around $550, with an MSRP of $700. Current listings range from approximately $400 to $570, with some prices as low as $400. Street prices run considerably lower than MSRP.
What is the difference between the Mossberg 590 and 590s?
The 590S features a redesigned elevator and bolt slide with an energy-absorbing bumper, allowing it to reliably cycle 1.75-inch mini shells alongside standard 2.75 and 3-inch rounds in any combination. The original 590 cannot handle mini shells. Both share identical external controls and safety features.
What are the pros and cons of a 590s shockwave?
Pros: compact pump-action design, handles 1.75-inch mini shells plus standard rounds, reliable operation, good safety placement. Cons: short barrel limits range, pistol-grip ergonomics take practice, recoil management requires technique. Best suited for close-quarters defense or specialized shooting.
Is the Mossberg 590s shockwave legal?
Federal law classifies the 590S Shockwave as a firearm, not a short-barreled shotgun, so it requires no NFA tax stamp. However, state and local laws vary—some jurisdictions restrict or ban it entirely. Check your state and local laws before purchasing.
What are the best upgrades for a shockwave?
Popular upgrades include tritium sights for low-light shooting, a pistol brace for better control, a heat shield for barrel protection, and an aftermarket pump handle for faster cycling. Keep additions minimal to preserve the Shockwave's compact handling advantage.
What are the reviews of the Mossberg 590S shockwave?
Reviewers generally praise the 590S Shockwave for its reliability, compact size, and ability to chamber 1.75-inch, 2.75-inch, and 3-inch shells. Users highlight solid build quality and practical defensive utility. Some note the pistol-grip configuration makes recoil management challenging for inexperienced shooters. Overall reception is positive among home-defense and range enthusiasts.
Can I shoot slugs out of my Mossberg 590?
Yes, the Mossberg 590 handles slugs well. Rifled Foster slugs work reliably through the smooth bore. Sabot slugs require a rifled barrel for accuracy. Avoid extra-full choke tubes due to excessive constriction. A cylinder or improved cylinder choke is recommended for best results.
What is the barrel length of the 590S Shockwave?
The 590S Shockwave has an 18.5-inch barrel. It features a 3-inch chamber accepting 1.75-, 2.75-, and 3-inch shells, and is classified as a firearm rather than a shotgun due to its overall length and pistol grip configuration.
Is the Mossberg 590S reliable?
The 590S is generally reliable. It uses Mossberg's proven pump-action platform and handles 1.75-inch mini shells alongside standard 2.75-inch and 3-inch loads without issues. Users report consistent performance for defensive and range use. Street price runs around $500–$600.
Is it legal to put a vertical grip on a shockwave?
Adding a vertical foregrip to a Mossberg Shockwave is a legally unsettled question. Some argue it would create an AOW requiring NFA registration; others contend it would not, since the Shockwave is not classified as a pistol. The Shockwave is legal as configured. Consult a firearms attorney before modifying it.
Is a Mossberg 590 shockwave considered a pistol?
No. The Mossberg 590 Shockwave is federally classified as a "Pistol Grip Firearm" for ATF Form 4473 and A&D records, requiring no NFA tax stamp. However, some sources classify it as a pistol firing shotgun ammunition, and certain state or local laws may treat it as a short-barreled shotgun or assault weapon. Check your local laws.
Can you put a full stock on a Mossberg shockwave?
Adding a full stock to a Shockwave reclassifies it as a short-barreled shotgun under federal law, requiring NFA registration and a $200 tax stamp. The Shockwave's 14" barrel is specifically designed to avoid this classification. Laws vary by state, so consult a firearms attorney before modifying it.
What are the different models of the Mossberg 590 shockwave?
Mossberg makes several 590 Shockwave variants, including the standard 590 Shockwave, 590 Shockwave SPX, 590 Shockwave Laser Saddle, 590 Shockwave 7-Shot, 590 Shockwave Flat Dark Earth, 590 Shock 'N' Saw, 590 Nightstick, and models chambered in .410 bore and 20-gauge, in addition to the standard 12-gauge.
Do all Mossberg 590s have metal trigger guards?
No. Standard Mossberg 590s have plastic trigger guards. The M590A1 military-specification variant upgrades to a metal trigger guard and metal safety button. The standard plastic components are functional and corrosion-resistant but do not meet military contract specifications.
