"You had better clean it and load it...it is as well to be ready for anything." - Sherlock Holmes & Dr. Watson - "A Study in Scarlet". The kind of revolver that Dr. Watson carries with him when he and Holmes go out on their cases has been a matter of debate for decades. As a medical-officer (MO) for the British Army, he certainly would have been issued with a sidearm (service revolver) for the purposes of self-defence. However, Doyle never once mentions anything about what kind of revolver Watson carried. I have reason to believe that Watson's revolver was either a Beaumont-Adams revolver or an Enfield revolver, both of which were service-revolvers in the British Army in the 1870s-1880s. Since Watson was injured in the line of service circa 1880 in the Battle of Maiwand, he must have had one of these as his sidearm.
