Mossberg Shockwave: Compact 12 Gauge Shotgun for Tactical Defense

Compact defensive shotguns occupy a specific niche for homeowners, vehicle operators, and those needing a reliable short-range tool. The right choice balances handling, ammunition flexibility, and legal awareness—especially with non-traditional layouts that trade a shoulder stock for a pistol-style grip.

MOSSBERG 590 Shockwave is a pump-action, short-barrel shotgun built around a distinctive bird’s-head (“Raptor”) pistol grip and a compact overall length of roughly 26 inches. The factory barrel measures approximately 14.375 inches and the platform accepts both 2 3/4″ and 3″ 12 gauge shells (verify your model marking). Common magazine capacity runs 5+1 depending on shell length, and unloaded weight falls in the 5.0–5.5 lb range.

Key features explained

MOSSBERG 590 Shockwave is designed as a close-quarters defensive tool. Its pump-action reliability pairs with a simple bead front sight on many versions; some editions include a short Picatinny rail or ghost-ring rear sight on special models for optics or lights. Receivers come in parkerized or Cerakote finishes depending on package, and most Shockwaves use a cross-bolt safety. Many have a fixed factory choke—confirm before purchasing choke tubes or muzzle devices.

Tactical handling and accessory options

The bird’s-head grip improves one-handed manipulation and storeability in vehicles or bedside setups. Some Shockwave variants offer short rails for weapon lights or micro-red dots; keep overall weight and balance in mind when adding accessories. Many owners appreciate the platform’s simplicity—minimal controls and a predictable pump cycle.

Legal and safety considerations

Do not add a shoulder stock or otherwise convert this design without verifying federal and state/local law. Adding a stock can reclassify the firearm as a short-barreled shotgun (NFA in the U.S.). Some states restrict Shockwave-style firearms—check local regulations before buying, modifying, or transporting.
