The Stevens 320 Security is a full-size 12-gauge pump shotgun built tough for home defense and tactical applications. This is a no-nonsense working gun: a 18.50-inch barrel, all-matte-black finish, and a fixed synthetic stock that won't break the bank or your shoulder. The 320 Security platform has earned its reputation through years of real-world use, and this version brings a redesigned stock and fore-end to the tested pump-action design that makes it reliable enough to count on when it matters.
What sets the 320 Security apart is its engineered simplicity. The rotary bolt and dual slide-bars—the same mechanism that's proven itself in countless shotguns—keep things running smooth through whatever you throw at it. A 5+1 capacity (five rounds in the tube, one in the chamber) gives you solid firepower without excess weight, and the ambidextrous design means lefties and righties both get a comfortable, natural fit. At 6.7 pounds and 39.3 inches overall, it's manageable in tight spaces but substantial enough to handle the recoil of full-power loads.
The aluminum receiver paired with the chrome alloy steel barrel keeps the weight down while resisting corrosion. Bottom-loading tube magazine and right-side ejection are exactly what you'd expect from a purpose-built defense shotgun. If you need a shotgun that does one job well—securing your home or defending what matters—without paying for features you'll never use, the Stevens 320 Security delivers.

Yes. The 18.50-inch barrel is short enough for tight hallways and rooms, the pump action is simple and reliable, and the 5+1 capacity gives you plenty of firepower. The ambidextrous controls and comfortable stock make it equally suited to left and right shooters under stress.
The Stevens 320 Security has a 3-inch chamber, which means it will safely fire both 2.75-inch and 3-inch loads. Always verify ammunition compatibility and follow the manufacturer's guidance for your specific loads.
The length of pull is fixed at 13.75 inches. The stock is not adjustable, so be sure it fits your proportions before purchase.
Yes. The 320 Security is fully ambidextrous, with controls positioned for both left and right-handed operation. The right-side ejection is standard for pump shotguns and works well for either hand orientation.
