Mossberg 590M Shockwave now has Detachable Magazine

Mag-Fed, Pump-Action 12-Gauge
The new non-NFA pump-action 12 gauge includes a 15-inch barrel and 10-shell detachable box magazine as standard options.

Announced recently, Mossberg has added a detachable double-stack magazine to its 590M Shockwave.
Showcasing its raptor-style pistol grip on a pump-action is not only do-able but fun to shoot. Combine this with the new series of detachable double-stack magazine of 10, 15 or 20-round capacity mags. Which has an ambidextrous magazine release button for easy unload and reloading.
You now have plenty of slugs for shooting paper targets or for home defense.
The 590M features a safety strap on the corn cob fore-end along with sling swivel studs.
Designed for use with 2.75-inch shells only, the mags are polymer with a self-lubricating body, hardened steel feed lips, and integral stabilizing ribs.

MSRP at $721, it should be a hit.
