The Boss & Co external-hammer SxS in 20 gauge is a Victorian-era sporting shotgun produced during the percussion-to-centerfire transition period. These lighter-gauge hammer guns were used for partridge and snipe shooting where a smaller, faster-handling gun was preferred. Boss's Victorian hammer guns in 20 bore are among the finest examples of the type from any maker.
