20 gauge is a lighter, lower-recoil shotgun chambering, popular for upland hunting, smaller-framed or newer shotgunners, and general-purpose use.

The 20 gauge is a smaller shotgun bore than the 12 gauge, firing lighter shot payloads with noticeably less recoil. That softer recoil and the typically lighter gun weight make it a common choice for upland bird hunting, younger or smaller-statured shooters, and anyone who wants an easier-shooting shotgun. It is also used for home defense and clay sports. Ammunition is widely available, though the selection is somewhat narrower and sometimes pricier than 12 gauge. It suits shooters who value a lighter, gentler-shooting shotgun and do not need the heaviest payloads.
