When the Mossberg SA-20 easily came out on top, no one was more shocked than I, compared to other 20 gauge autoloaders in the recent Battle of the 20 Gauge Autoloading Shotguns, but it did just that. Not only is it the best value on the market for a 20 gauge hunting autoloader, it is the best, regardless of cost. Not always has it been that way. Nine years ago, in 2008, the SA-20 was introduced. I didn't care about it in particular, as loading was a hassle. You had to push the bolt release button after chambering the first round to release the shell elevator to press a shell into the magazine, then repeat the sloppy button-pressing for subsequent rounds.

Style and Appearance * * * *


Plain wood grain in the walnut stock, but nice color and finish.

Customization * * * *


The ability to make major stockfit changes is a real plus on a gun of this price. A drilled receiver and sling swivels would have been nice, especially in a field gun.

Reliability * * * * *

After 1,000+ rounds of mixed Remington, Winchester, and Federal shot shells, no issues at all. Low-recoil loads worked fine, too.
Accuracy * * * * * BUY PISTOLS & SHORTGUN SCOPES


It takes some patience to get the gun fit correct to see the top of the vent rib perfectly, but it’s doable without getting the stock bent.

Overall * * * * 1/2
The Mossberg International SA-20 is a very good value for the money. It’s lightweight and customizable enough to fit most any shooter. The lack of sling swivels on a field gun is the only glaring miss.
