The slide markings on a Remington Rand 1911A1 underwent two distinct variations, helping collectors identify the pistol's production period. Share public link A stamped "S" and "P"

— By far the most common variation, the Type III uses the same legend as the Type II ("REMINGTON RAND, INC. / SYRACUSE, N.Y. U.S.A.") but in a smaller font. The overall length is reduced to approximately 1 inch, making it significantly shorter than the slide stop. This final version was introduced at about serial number 955,000, and by around 1,016,000 and beyond, it became the standard marking.

Remington Rand serial numbers run from approximately to 2,465,139 , with production ending in 1945. Early production pistols featured a distinctive "NO." prefix before the serial number. A notable characteristic is a faint line extending from the "O" in "NO" across the frame—a subtle but useful authenticity indicator for early pistols.
