and colonial conflicts due to the stopping power of its larger 54 bore (.442 cal) bullet (compared with their main competitor, the smaller .36 cal Colt Navy revolvers), and the speed of the Adams trigger-cocking action for close-quarters fighting (over the more cumbersome Colt action). In partnership with George and John Deane, the company of Deane, Adams & Deane produced the new revolver in a variety of calibres and sizes, from pocket pistols to large military versions. The United Kingdom officially adopted the 54-bore (.442 calibre) Beaumont–Adams in 1856, Holland and Russia following soon after. To meet the growing demand for its weapons, Deane, Adams & Deane contracted companies in Birmingham and Liége to manufacture their weapons under licence. The new revolver gave Robert Adams a strong competitive advantage and

. They also made a pocket version in .32 calibre. In 1867, Robert Adams' brother John Adams patented a breech-loading revolver which was adopted by the British government in place of the Beaumont–Adams. It was a solid frame pistol with six chambers, in .450 caliber. After official acceptance of his pistol, Adams left the London Armoury Company and established his own factory, the Adams Patent Small Arms Company. His pistol was manufactured in three distinct variations (differences related mainly to methods of spent cartridge ejection) between 1867 and about 1880. The models were tested and adopted by the British Army and Navy, with the last, the M1872 Mark III, seeing the widest use. The John Adams revolver remained the official sidearm of the British Army until replaced by the Enfield Mark I in 1880.
