Originally manufactured by one of the U.S. contracted firms to produce the U.S. M1911A1 (Colt or Remington-Rand), this pistol was subsequently extensively reworked and upgraded to National Match specifications by the U.S. Rock Island Arsenal in Illinois. Unlike most arsenal M1911A1 NM pistols, this example was upgraded a step further as a National Match Trophy pistol, finished with an attractive deep blue finish with high polish sides contrasted with matte along the dorsal and ventral lines as well as bright sides on the hammer. As a trophy pistol, it would have been awarded to a winning competitor in the matches as a more appealing prize than a standard static trophy. Features serrated Patridge blade front sight and "US" marked Elliason adjustable rear sight, "7267718/NM" marked barrel bushing, "NM 7791414" marked barrel with only the "5" portion of "45 AUTO" on the top line remaining, along with "M P" and "C squared" on the recoil lugs, "RIA" and "NM" marked on the right of the frame and trigger guard, flared magazine well, checkered front strap, standard M1911A1 pattern controls, and the serial number "922858" marked on the interior on the slide and frame. The magazine is marked with a partial "858" in electro pencil. Fitted with a pair of checkered walnut grips. Included with the pistol is a oiled walnut display case, with silver plaque marked " ROCK ISLAND ARSENAL/NATIONAL MATCH/TROPHY PISTOL", fit for the pistol and accessories with blue felt, three extra magazines, extra springs, extra trigger, extra "7267718/NM" marked barrel bushing, extra trigger link, cleaning rod, and keys for the case.

Extremely fine as upgraded into a National Match trophy pistol by the U.S. Rock Island Arsenal, retaining 97% plus contrasting high polish and matte deep blue finish with limited minor edge wear and handling marks, along with light cycling wear. the grips are also excellent with crisp checkering and minor handling evidence on the right panel. The case is very fine. Mechanically excellent. National Match Trophy pistols such as this are hard to come across, and would traditionally require a winning score at the matches in order to posses.
