Who This Is For

Frequently Asked Questions
How does the 20 gauge Mossberg 590 compare to the 12 gauge version for home defense?
The 20 gauge 590 offers the same legendary Mossberg reliability and nearly identical terminal performance at typical home-defense distances, while producing noticeably less recoil than a 12 gauge. This makes it faster to get back on target for follow-up shots and more comfortable for shooters who are recoil-sensitive. Modern 20 gauge defensive loads — including reduced-recoil buckshot and slugs — are highly effective and widely available.
What types of ammunition can the Mossberg 590 20 gauge chamber?
With its 3" chamber, this shotgun accepts both 2¾" and 3" 20 gauge shells, giving you maximum flexibility. You can run standard birdshot for practice, buckshot loads like #3 Buck for home defense, or rifled slugs for greater range and penetration. Always verify that your chosen load is appropriate for your intended use and that your choke (if used) is rated for that load type.
Can I add accessories like lights or a different stock to this shotgun?
Yes. The Mossberg 590 platform has one of the largest aftermarket ecosystems of any pump-action shotgun. A wide range of compatible forends — including tri-rail versions that mount tactical lights and lasers — are available directly from Mossberg and third-party manufacturers. Stocks can also be swapped for adjustable or pistol-grip configurations, and the ghost-ring sight versions accept Picatinny-compatible optics mounts. Always ensure any accessory is rated for 20 gauge use.
