 Sometime in the 1890s, Rigby sold his Dublin operations to Trulock & Harriss (keeping, however, his customers in Ireland) and became a bona fide member of the small circle of elite gunmakers who catered for London society.Like his grandfather, the third John Rigby was a top target shot and developed the Rigby Target Rifle for competition use.He won several Wimbledon Cups (the premier long-range rifle championship in the United Kingdom) and, for 28 years, he helped form the Irish national shooting team.
