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.

What distinguishes the Adams MkIII from earlier Adams revolvers?

The Adams MkIII, developed in 1872, was a purpose-built centerfire cartridge revolver. It evolved from Robert Adams' earlier percussion designs, with John Adams developing the two-part frame that simplified manufacturing for the centerfire MkIII.

How can one identify an NWMP-issued Adams MkIII revolver?

Key identifiers include British military proofs ('WD', broad arrow), a date stamp (like '3-74'), and crucially, the 'C MP' marking, likely standing for Canada Mounted Police, alongside a Canadian serial number.

Why are NWMP Adams MkIII revolvers considered scarce today?

The Adams MkIII had a relatively short primary service life with the NWMP, being replaced by Enfield revolvers by 1880. With only 326 issued, surviving examples marked for the NWMP are exceptionally rare.
