Boss & Co was established in 1830 and has produced side-by-side sidelock guns to the highest standard since the percussion era. The contemporary Boss SxS Sidelock in 12 gauge continues this tradition, featuring Boss's own patent single trigger, long-horn sidelocks, and gold-lined action body with gold-oval name panel. Built on Boss's traditional principles — the same principles that informed their groundbreaking O/U development — the SxS remains a benchmark for British gunmaking.
