The gas system is a key differentiator here. While inertia-driven shotguns like the Franchi Affinity are popular, a gas system like the SA-20’s soaks up more recoil—a real benefit for smaller-framed shooters or those putting in long days at the range or in the field. The 5.5-pound weight makes it easy to carry all day, and the 26-inch barrel strikes a solid balance between swing dynamics for clays and maneuverability in a blind. Here’s the thing—you’re getting Mossberg’s proven reliability in a package that doesn’t demand a premium.
Who This Shotgun Is For
This shotgun is ideal for the budget-conscious upland hunter, new waterfowler (where non-toxic shot is required), or a recreational clay shooter looking for a soft-shooting, reliable semi-auto. It’s also a fantastic option for younger shooters or those with a smaller build who benefit from the 20-gauge’s milder recoil and the gun’s lightweight design. If you want a dedicated, no-fuss field gun that looks good and won’t break the bank, this Mossberg hits the mark.
Pros & Cons: The Practical Trade-Offs
Pros: The standout advantage is the price-to-performance ratio. You get a name-brand, gas-operated semi-auto for hundreds less than many competitors. The recoil reduction is tangible. The Muddy Girl finish is durable and provides good concealment in brush. Its light weight and 26-inch barrel make it highly portable and quick-handling.
Cons: To hit this price, some features are simplified. The finish, while tough, isn’t a premium-grade cerakote. The synthetic stock, though durable, may not have the precise ergonomic adjustments of higher-end models. It may also be more sensitive to maintenance than an inertia system—keeping the gas system clean is important for reliable function. That said, for $443.95, these are expected and reasonable compromises.
Frequently Asked Questions
Q: Is the Mossberg SA-20 reliable with light target loads?
A: Yes, the gas-operated system is typically very reliable with standard 2 3/4″ target loads (7/8 oz or 1 oz), which is a major advantage for clay shooters or those wanting low-recoil practice. It’s a more versatile system across load types than some budget inertia guns.
Q: Can I use this for duck or goose hunting?
A: Absolutely, provided you use steel or other approved non-toxic shot. The 3″ chamber allows for heavier waterfowl loads. The 26″ barrel is a common choice for waterfowling, and the Muddy Girl pattern offers decent concealment in marsh environments. Just be sure to check your local regulations for any gauge restrictions.
Q: What chokes does it come with, and are they interchangeable?
A: The SA-20 typically comes equipped with a set of Accu-Choke tubes (often Improved Cylinder, Modified, and Full). These use the common Benelli/Beretta Mobil-style choke thread pattern, meaning you have a huge aftermarket selection of chokes from brands like Carlson’s, Trulock, and Patternmaster for specialized hunting or competition.
