The John Rigby & Co SxS Sidelock in 20 gauge is a lightweight game gun built to the same standards as the 12-bore. Rigby's 20-bore SxS suits the Highland stalker who also shoots driven game and needs a lighter gun than the 12-bore for walked-up conditions. The gun is fitted individually to the client's dimensions at the Rigby workshop.
