Excellent Early World War II Era "R.S." Inspected U.S. Colt Model 1911A1 Semi-Automatic Pistol The Model 1911A1 was a refinement of the John Browning designed Colt Model 1911 and saw extensive use in World War II, the Korean War, and Vietnam as well as use by Special Operations units during the Global War on Terror. The 1911 remains the most iconic American semi-automatic pistol of all time and a trusted sidearm of countless Americans. The early U.S. military contract Colt Model 1911A1s featured the firm's beloved high polish blue finish, but the Robert Sears inspected Model 1911A1 pistols saw the transition from the high polish blue to the more durable Parkerized treatment that became the standard for the rest of World War II production. This example, manufactured in 1941, received the blue finish before the transition. It falls within the serial number range 729,478 to 731,027 of 1,550 pistols listed on page 396 of "Colt .45 Service Pistols" by Charles W. Clawson as shipped to the U.S. Springfield Armory on May 29, 1941. The pistol features fixed blade front and notch rear sights, a blued barrel marked "COLT 45 AUTO" on the left side, "G" on the underside, and with "P" on the recoil lug; the standard two-line, two-block Colt address and patent dates with the Rampant Colt in the center on the left of the slide, "P" on top of the slide, the matching serial number under the firing pin stop, and a checkered thumb safety, slide stop, wide spur hammer, short milled trigger, and arched mainspring housing with lanyard loop at the bottom. The left of the frame bears a double struck boxed "R.S." (Robert Sears) inspector mark and "P" proof, and another boxed "R.S." inspector mark is repeated on the top of the frame under the slide. The right side bears the serial number, model, and U.S. property markings. The left of the trigger guard is marked with "T" over "triangle/VP", and a "69" is marked on the right side. The pistol is fitted with a pair of correct brown checkered plastic "hollow back" grips and a full-blued magazine marked "S" on the toe.
