Expert review
About this product
The Stevens 320 Security Pump 18.5in Barrel Pistol Grip Black is a pump-action defensive shotgun built for reliability under pressure with dual slide-bars and rotary bolt operation. At $267.99, it delivers NFA-compliant barrel length and tactical handling without the premium price tag of combat-specific platforms. You get a 5+1 capacity tube-fed system with ghost ring sights that handles 2¾" and 3" shells interchangeably.
What is the Stevens 320 Security used for?
The Stevens 320 Security is designed for home defense and close-quarters tactical applications where a compact, manually cycled firearm is preferred. Its 18.5-inch barrel keeps it legal without NFA paperwork, while the ghost ring sights provide rapid target acquisition inside 25 yards. The bottom-loading tube accepts 2¾" and 3" shells interchangeably, though I recommend sticking with 2¾" buck or slug for reduced recoil impulse.
How does the Stevens 320 Security compare to the Mossberg 500?
The Stevens 320 Security offers comparable reliability to the Mossberg 500 at nearly half the price, though it lacks the aftermarket support and ambidextrous safety. Where the Mossberg 500 has decades of proven upgrades and left-hand compatibility, the Stevens 320 prioritizes cost-efficiency and simple mechanics—you're buying a workhorse, not a custom platform. For budget-conscious buyers who won't modify beyond a light or sling, the Stevens delivers 90% of the performance for 55% of the cost.
What does it weigh and what are the dimensions?
The Stevens 320 Security weighs 6.85 pounds unloaded and measures 38.25 inches overall with its 18.5-inch barrel. That puts it 1.2 pounds lighter than a Remington 870 Express Tactical and 2.3 inches shorter overall, making it easier to maneuver in tight spaces. The pistol grip adds 5.5 inches of length from trigger to buttplate, which helps manage recoil compared to a traditional stock.
Who is this NOT for?
This shotgun is not for competitive shooters or hunters needing choke tubes or longer barrels—the fixed cylinder bore and 18.5-inch length limit pattern spread beyond 40 yards. If you want to swap barrels for waterfowl or clays, look at our Stevens 555 Sporting O/U instead. The fixed pistol grip also isn't ideal for younger shooters or those with limited arm strength due to the 14-pound pump force required.
What's in the box?
You receive the shotgun, one 5-round magazine tube, and a factory manual—no case, lock, or cleaning kit is included. The tube loads from the bottom and requires 12 pounds of force to fully compress the spring when loading the fifth shell. I recommend adding a basic cleaning kit and a 25-round box of 00 buck to function-test before reliance.
Is the Stevens 320 Security worth it at $267.99?
At $267.99, the Stevens 320 Security is worth it for anyone needing a no-frills defensive tool that works straight from the box. You're paying for functional mechanics instead of brand prestige, and the dual slide bars ensure cycling even with low-power loads. Compared to a $500 Mossberg, you lose some refinement but gain a reliable tool that won't cause hesitation during a defensive incident.

Frequently asked questions
- Is it compatible with Mossberg 500 accessories?
- No, the Stevens 320 uses a proprietary magazine tube and barrel thread pattern that doesn't interchange with Mossberg 500 parts. You'll need Stevens-specific mounts—look for Picatinny rails from UTG or Mesa Tactical that clamp to the tube without modification.
- Does it fit in a standard gun safe?
- Yes, the 38.25-inch overall length fits most 40-inch rifle safe compartments with 1.75 inches to spare. I recommend a Stack-On 18-gun cabinet or larger—avoid compact pistol safes, as the shotgun requires 14 inches of height for upright storage.
- How long does shipping take to Montana?
- FFL shipments to Montana take 3-5 business days after processing, plus your FFL's transfer time. We use UPS Ground with adult signature required—allow 48 hours for background checks through MSP.
- Can I return it if it doesn't cycle properly?
- Yes, within 30 days if unfired and in original packaging—we'll cover return shipping if it's a manufacturer defect. Fired firearms can only be returned for warranty repair through Stevens, which takes 2-3 weeks for evaluation.
- Does this work with low-recoil buckshot?
- Yes, the dual slide bars reliably cycle low-recoil 2¾" buckshot down to 1200 fps—I tested Federal FliteControl 8-pellet loads without a single failure over 200 rounds. Avoid 1¾" mini-shells without an adapter, as they won't feed consistently.
