Mounties' First Revolver: the NWMP Adams MkIII
The Adams MkIII revolver was the first truly modern sidearm issued to the North-West Mounted Police (NWMP) in late 1874, replacing unreliable converted cap-and-ball models. Developed by John Adams based on his brother Robert's earlier designs, this centerfire revolver featured a solid frame and double-action trigger. Despite its advanced design for the era, its service life was short, making original NWMP-marked MkIIIs scarce today.
