Remington Arms was contracted to produce M1911 pistols during WWI to supplement Colt production, though Remington UMC (Remington's ammunition subsidiary) produced only about 21,677 pistols before the Armistice ended the contract. These WWI-era Remington UMC M1911s are among the rarest 1911 variants, distinguishable by the Remington UMC marking on the slide. They are highly sought by 1911 collectors and WWI military artifact collectors.
