## What Customers Say

*AI-generated insights from customer reviews*

The 590S Shockwave gets a mostly positive reception, with some consistent caveats that potential buyers should weigh.

The compact size and light weight are the most praised qualities. Owners who need something maneuverable for home defense or vehicle storage find the 30.75-inch overall length very practical. The birdshead Raptor grip improves handling over a standard pistol grip, and most owners adjust to it quickly. Reliability with various ammunition types is generally well-rated, consistent with Mossberg's reputation.

The recoil is real and comes up regularly. Without a stock to distribute the force, 12-gauge loads hit harder than the same shell fired from a full-stock shotgun. Most owners recommend starting with lighter loads. Some also note that the 590S designation's multi-shell compatibility is genuinely useful and sets this model apart. Customization with lights or slings is possible and discussed frequently, though some modifications can create legal complications in certain jurisdictions - worth researching before adding accessories.
