The shotgun’s overall length is compact, typically around 38-39 inches, making it highly maneuverable in confined spaces. Its weight, usually just under 7 pounds, strikes a good balance between being light enough to handle easily and heavy enough to soak up some of the 20-gauge’s manageable recoil. The 20-gauge chambering is a practical choice—it delivers substantial defensive power with less kick than a 12-gauge, which can be a major advantage for shooters of smaller stature or those sensitive to recoil. The ghost ring sight is a standout upgrade over a simple bead, giving you a real fighting sight picture. Look, the value here is clear when you stack it against a Mossberg Maverick 88 Security or a basic Remington 870 Express; you’re getting a specialized thumbhole stock and tactical sights for a similar or lower price point.
Who This Shotgun Is For
This is a purpose-built tool for the budget-conscious defender. It’s ideal for a Missouri homeowner seeking a reliable, no-frills home defense firearm that’s easier to handle than a 12-gauge. It’s also a solid choice for a new shooter who wants to build confidence with a pump-action platform that has less intimidating recoil. The thumbhole stock offers a more modern, controlled grip than a traditional straight stock, appealing to those who prefer that ergonomic style for security applications. It is not a hunting gun, nor is it a competition shotgun—it’s built for a specific defensive role.
Pros & Cons
Pros: Exceptional price-to-performance ratio. The 20-gauge offers effective stopping power with reduced recoil, making follow-up shots easier. The ghost ring and thumbhole stock are features typically found on more expensive tactical models. The 18.5-inch barrel keeps it legal and handy. Simple operation means high reliability with minimal maintenance.
Cons: Aftermarket support for the Stevens 320 platform isn’t as vast as for the Mossberg 500 or Remington 870. The thumbhole stock design is a fixed feature—you can’t easily swap it for a traditional stock or pistol grip configuration. Some users may find the thumbhole less familiar than a standard stock. That said, for the price, you’re getting a complete, ready-to-go package.
Frequently Asked Questions
Frequently Asked Questions
Q: Is the thumbhole stock comfortable for shooters with smaller hands?
A: Generally, yes. The thumbhole design can actually provide a more natural and secure grip point than a traditional stock for many shooters, as it encourages proper hand placement. The 20-gauge’s milder recoil also helps with control. It’s always best to handle one if possible, but the ergonomics are a key selling point for this model.
Q: Can I use this for hunting or clay shooting?
A: While you could technically use it, it’s not ideal. The 18.5-inch cylinder bore barrel will throw a very wide, short-range pattern, making it ineffective for most bird hunting or clay sports where longer shots and specific chokes are needed. This is a dedicated security/defense firearm with sights and a stock optimized for that role.
Q: What kind of ammunition should I use for home defense?
A: For a 20-gauge defensive load, look for quality buckshot like #3 buck. It provides a good balance of pellet count and penetration. Many also recommend Federal’s FliteControl 20-gauge buckshot loads for tight, consistent patterns. Always pattern your chosen load at the range to understand its performance. Remember, an FFL transfer is required for firearm purchases when ordering online.
If you need a dependable, affordable defensive shotgun that comes ready with practical tactical features, the Stevens 320 Security Thumbhole Pump in 20-gauge is a compelling option to consider. Check availability at firearms-missouri.com for Missouri residents and nationwide.
