Key Features
- Mag-Fed System — Why it matters: Reloads are faster than tube-fed shotguns, letting you swap in a fresh magazine in seconds instead of fumbling with individual shells.
- 15-Inch Heavy-Walled Barrel — Why it matters: The shorter barrel keeps the shotgun compact for tight spaces, while the heavy wall reduces recoil and improves durability for extended use.
- Shockwave Raptor Bird’s-Head Grip — Why it matters: This ergonomic grip gives you a stable, controlled hold without a traditional stock, making the firearm easier to maneuver and shoot accurately one-handed if needed.
- Drilled-and-Tapped Receiver — Why it matters: You can mount optics or a red dot sight directly to the receiver, improving target acquisition speed in low-light or defensive situations.
- Steel Construction with Anti-Corrosion Finish — Why it matters: The all-steel receiver and matte blued finish stand up to harsh weather and heavy use, ensuring the shotgun stays reliable season after season.
Who It’s For
This shotgun is built for southern shooters who want a compact, fast-handling defensive tool for home or vehicle. Bird hunters might appreciate it as a backup gun for thick cover, but its real strength is in personal protection. If you value quick reloads and a short barrel without sacrificing pump-action dependability, the 590M Shockwave fits the bill.
Pros & Cons
- Pros: Fast magazine changes; compact and lightweight; durable steel receiver; optics-ready; reliable pump action.
- Cons: Magazine cost is higher than traditional tube-fed shotguns; the bird’s-head grip takes practice to shoot accurately compared to a full stock.

FAQ
Is the Mossberg 590M Shockwave legal in my state?
It depends on local laws. The 15-inch barrel and bird’s-head grip classify it as a firearm, not a short-barreled shotgun, under federal law. However, some states restrict overall length or require a tax stamp. Check your state regulations before ordering.
What magazines work with this shotgun?
Only Mossberg 590M magazines are compatible. They come in 5-round and 10-round capacities. Aftermarket options are limited, so stick with factory mags for best reliability.
Can I mount a red dot sight on the 590M Shockwave?
Yes, the receiver is drilled and tapped for optics. You can mount a red dot or reflex sight using a standard shotgun base. This improves accuracy in defensive situations.
How does the mag-fed system affect reliability?
The pump action remains the same as the Mossberg 590, which is known for reliability. The magazine adds a potential failure point, but factory mags are well-made. Keep them clean and loaded for best performance.
Is the Shockwave Raptor grip comfortable for extended use?
It takes some getting used to. The bird’s-head grip reduces recoil compared to a pistol grip but doesn’t offer the same stability as a full stock. Practice at the range to build muscle memory.
