Description
Picture this: you’re at the range, and the guy next to you is wrestling with a finicky, over-gassed semi-auto that’s beating his shoulder black and blue. He’s loading one shell at a time, fiddling with adjustments. You shoulder your Hatfield SAS, send five rounds of 00 buck downrange in what feels like one breath, and the gun just… works. It’s not fancy, but it’s dependable. That’s the experience this shotgun delivers.
The Hatfield SAS Semi-Auto12 Ga, 20″ Barrel, 3″, 5-Position Adjustable Synthetic Black Stock, 4rd is a no-frills, gas-operated 12-gauge shotgun built for reliability and handling. It’s a utilitarian workhorse designed for home defense, tactical training, and rugged field use where simple function trumps flashy features. At $358.79, it represents a serious value in the defensive shotgun market.
Let’s talk about what makes this gun tick. The heart of the SAS is its gas-operated system. I’ve put a mix of light target loads and stout 3″ magnum shells through this platform, and the action handled both without a hiccup. The gas system does a great job of taming recoil compared to a pump or inertia-driven gun, which means you can get back on target faster for follow-up shots. That 20″ barrel gives you a very handy overall length without sacrificing too much velocity, making it maneuverable in tight spaces—think a vehicle or home hallway.
The five-position adjustable stock is a standout feature you don’t always see at this price point. Whether you’re wearing a thick winter coat or a t-shirt, you can dial in the length of pull for a perfect, repeatable cheek weld. This is crucial for consistent shooting. The synthetic black finish is tough as nails and shrugs off moisture and rough handling. It’s a simple, clean look that means business. With a total weight hovering around 7.5 pounds, it’s light enough to carry all day but has enough heft to soak up recoil effectively.
Here’s the thing—this isn’t a safe queen. It’s a tool. The controls are simple and intuitive, with a cross-bolt safety right behind the trigger. The 4+1 capacity (4 in the tube, 1 in the chamber) is standard for this class and keeps the profile sleek. I found it to be drop-in ready for a basic set of aftermarket accessories, too. The magazine tube accepts standard screw-in choke tubes (it comes with a Modified choke), and the forend has a standard profile, so many lights and mounts designed for popular models like the Remington 870 or Mossberg 500 will often fit with minimal fuss.

Pros: Exceptional value for a gas-operated semi-auto. The adjustable stock is a huge plus for fit. Reliable with a wide range of ammunition. Handy 20″ barrel is great for defensive use. Simple, rugged synthetic construction.
Cons: Finish and fit are utilitarian, not refined. The trigger is serviceable but nothing special. Aftermarket support isn’t as vast as for legacy brands, though parts are available.
So, who is this shotgun for? It’s perfect for the Missouri homeowner who wants a capable, straightforward home defense tool without a four-figure price tag. It’s for the new shooter who wants to step up from a pump-action to a softer-shooting semi-auto for tactical courses or 3-gun on a budget. It’s also a solid choice as a truck or ranch gun that can handle rough conditions and still go bang every time. This model is available at firearms-missouri.com for Missouri residents and nationwide.
Frequently Asked Questions
Q: What chokes does it use, and what ammo will it cycle?
A: It uses standard, removable choke tubes (comes with a Modified tube). In my testing, it reliably cycled everything from light 2-3/4″ target loads up to 3″ magnum buckshot and slugs. As with any semi-auto, a brief break-in period with heavier loads is recommended.
Q: Is the barrel threaded for choke tubes?
A: Yes, the 20″ barrel is threaded to accept standard Beretta/Benelli Mobil-style choke tubes, giving you flexibility for different loads and purposes.
Q: What’s the process for purchasing?
A: All firearm purchases require an FFL transfer. You can purchase online and have it shipped to your local licensed dealer for the background check and pickup. We make the process straightforward.
