The Mossberg SA-20 is a lightweight, easy-handling semi-automatic shotgun built for hunters and sport shooters who want less recoil and faster follow-up shots without sacrificing field performance. Chambered in 20-gauge with a 3-inch capability, this gun brings down birds and small game with genuine knockdown power while staying forgiving on the shoulder—ideal for younger hunters, women, and anyone who prefers a softer shooting experience without compromise. The 26-inch ventilated rib barrel and bead sight keep your sight picture clean and your swing smooth across open fields and tighter cover alike.
Built on a gas-operated system, the SA-20 cycles reliably through a variety of 20-gauge loads, from light target rounds to full-power 3-inch magnums. The satin-finished walnut furniture gives it a classic, professional look that won't show up game, while the durable blued barrel resists the elements. At 6.5 pounds and 46.5 inches overall, it's quick to mount and won't wear you down during a long day in the field. The fixed 14-inch length of pull works well for standard adult shooters and makes it a natural choice for a household gun that multiple family members can shoot comfortably.
The included Sport Set choke lets you dial in your pattern for whatever you're hunting—tighter for distance, more open for close work—and the 5-round magazine capacity gives you room to work without being unwieldy. Whether you're jumping birds over a dog, hitting clay targets, or hunting waterfowl, the SA-20 is a no-nonsense shotgun that does the job without fuss.

Yes. The 3-inch chamber accommodates both standard 2.75-inch and magnum 3-inch loads, giving you flexibility with whatever ammunition you have on hand.

No, the length of pull is fixed at 14 inches. This works well for most adult shooters; if you need a shorter or longer fit, an aftermarket stock or spacer kit may be an option to explore separately.
The light recoil and manageable weight make it ideal for hunters and shooters who prefer a softer-shooting shotgun, including younger hunters, women, and anyone sensitive to recoil. It's equally at home for sport shooting and field hunting.
