20 Gauge semi auto shotguns are an excellent option for hunters and shooters looking for a lightweight, lighter-recoiling option. We have a plethora of 20GA shotguns for sale from quality companies like Benelli, Beretta, Franchi, CZ-USA, Sauer, and Stoeger. Though we have 20 gauge pump shotguns for sale, semi auto’s are a great option as they are lighter in recoil and the shooter does not have to manually cycle the gun.
