Originally produced by Colt in 1943, this pistol was subsequently selected for upgrade to a National Match competition-grade pistol. It is fitted with a serrated Patridge blade front and Elliason adjustable rear sights, with a Colt "NM7791435" slide, "7267718/NM" bushing, and "NM 7791414" barrel (numbered to the frame), and a "GHD" frame with "SA", "T", "P", and "NM" stamps. The second digit of the serial number appears to have initially been stamped as an eight by mistake and then corrected by Springfield Arsenal. Equipped with a long serrated adjustable trigger, serrated narrow hammer, checkered front strap and serrated mainspring housing, checkered grips and a full blue "L" magazine.
