Description
Picture this: you need a reliable, no-fuss home defense tool that won’t break the bank. You’re not looking for a showpiece; you need something that works, is simple to operate, and stores easily. For many Missouri homeowners and budget-minded shooters, the answer lies in a classic 20-gauge pump-action shotgun. That’s where the Stevens 320 Security 20 Ga 18.50″ 5+1 3″ Matte Blued Fixed Pistol Grip Stock Black Right Hand makes its case—offering serious capability at a price that’s hard to argue with.
The Stevens 320 Security is a 20-gauge pump-action shotgun designed for home defense and security. It features an 18.5-inch barrel, a 5+1 round capacity for 3-inch shells, a matte blued finish, and a fixed pistol grip stock. This configuration prioritizes maneuverability and control in close quarters, offering a potent yet manageable option for shooters sensitive to 12-gauge recoil, all at a highly accessible price point.
Let’s talk about what you’re actually getting for your money. The heart of the Stevens 320 is its robust, dual-action bar design—a feature borrowed from more expensive platforms like the Winchester 1300—which provides a smooth, reliable pump cycle. This isn’t a fancy gimmick; it’s a proven mechanical system that helps prevent binding and enhances durability. The 18.5-inch barrel keeps the overall length compact, perfect for navigating hallways or checking a property. At a total length of just over 38 inches, it’s easy to store in a closet or cabinet without sacrificing that critical legal barrel length for a non-NFA firearm.
Here’s the thing—the 20-gauge chambering is a smart choice for a wide audience. While a 12-gauge has undeniable power, the 20-gauge offers formidable stopping power with significantly less recoil and muzzle rise. This makes the 320 Security an excellent option for smaller-framed shooters, those new to defensive shotguns, or anyone who values faster follow-up shots. With modern defensive loads, the performance gap at home-defense ranges is minimal, but the shooter comfort gap is substantial. The fixed pistol grip stock further aids in control, allowing for a firm, one-handed grip if needed and making the shotgun easier to manage from unconventional positions.
The matte blued finish is all business, resisting glare and being easy to maintain. The shotgun comes ready to go—no gunsmithing required to get it into service. It accepts standard 20-gauge 2.75-inch and 3-inch shells interchangeably, giving you flexibility in your ammunition choice. Weighing in at approximately 6.5 pounds, it has a solid, reassuring heft without being cumbersome.

Frequently Asked Questions
Q: Can I use 2.75-inch shells in this shotgun?
A: Yes, absolutely. The 3-inch chamber means it can safely fire both 2.75-inch and 3-inch 20-gauge shells interchangeably. You can load lighter 2.75-inch target loads for practice and more powerful 3-inch defensive loads for duty.
Q: Is the stock removable or adjustable?
A: No, the pistol grip stock is fixed. This is a dedicated security configuration designed for close-quarters control rather than versatility for hunting or sport shooting. For a traditional stock, you would need to look at other models in the Stevens 320 line.
Q: What is the barrel threaded for, and can I add a choke?
A: The barrel is not threaded; it features a fixed cylinder bore choke. This provides the widest possible pattern at short range, which is desirable for home defense, but it is not suitable for tasks requiring a tighter shot pattern. It is not designed for aftermarket choke tubes.
