Frequently Asked Questions

What makes the 590 Shockwave CA different from a standard Mossberg 590?

The 590 Shockwave CA is specifically configured to comply with California firearm regulations, making it legal for purchase and ownership in the state. While it retains the legendary Mossberg 590 action — including dual extractors, twin action bars, and the top-mounted safety — its overall design and capacity are tailored to meet California's requirements, giving Golden State residents access to a trusted defensive platform without compromise on core reliability.

What types of 12-gauge ammunition can this shotgun handle?

The Mossberg 590 Shockwave CA is chambered for 3-inch 12-gauge shells, meaning it can cycle both standard 2¾-inch and 3-inch magnum loads. This gives you broad flexibility in ammunition selection — from lighter target and birdshot loads for practice, to buckshot and slugs optimized for home defense. Always verify that your chosen ammunition is rated for pump-action shotguns and consult the owner's manual for any restrictions.

Is the Mossberg 590 Shockwave CA a good choice for a first-time shotgun owner?

The 590 Shockwave CA can be an excellent first shotgun for responsible adults committed to proper firearm training. Its pump-action design is straightforward to operate, and the ambidextrous top-mounted safety is intuitive for new shooters. However, 12-gauge recoil can be substantial, especially with defensive loads, so new owners are strongly encouraged to begin with lighter practice loads and seek professional instruction to build confidence and safe handling habits.
