Handguns

The G.I. .45 in World War II

The .45 pistol saw widespread service in all theaters of the war and further cemented its stellar reputation as one of the finest military handguns of all time.

Conceived in the fertile mind of John Moses Browning, the .45 ACP U.S. Model of 1911 was the culmination of extensive testing around the turn of the 20th century to develop a military handgun to replace the still-potent, but hopelessly obsolete, Model 1873 SAA and its replacement, the anemic .38 Colt double-action revolver. Immediately upon its introduction into service, the new pistol was apparently something special.

This was evident in World War I when a large number of Doughboys arrived in France armed with .45 pistols along with their M1903 or M1917 service rifles. The potent short-range stopping power of the rugged and reliable M1911 proved its worth in many brutal close-quarter trench-warfare engagements. After the war, many .45s went home in the duffel bags of members of the American Expeditionary Force. Although it performed superbly in the woefully misnamed “War to End All Wars,” some changes were recommended, including slight modifications of the sights, frame, trigger, hammer and mainspring housing.

By 1926 these various modifications were instituted, which resulted in the newly updated pistol’s nomenclature being changed to “M1911A1.” A May 17, 1926, Ordnance Dept. directive stated: “[A]s a means of ready distinction between the two models, it is agreed that all pistols bearing serial numbers under 700,000 should be designated as 1911 pistols, while pistols beginning at 700,000 should be designated M1911A1 pistols.” Even after standardization of the new variant, there were ample numbers of M1911s in the government’s inventory to meet the rather limited demands of our pared-down military between the wars, and Colt did not begin quantity production of the revamped M1911A1 until 1937.

As it became apparent to all but the most myopic observer that the United States was being inexorably drawn into World War II, demand for all manner of military arms, including pistols, increased dramatically. As Colt began to ramp up production of the M1911A1, the Ordnance Dept. made plans for a number of other commercial firms to manufacture the pistol as well. For example, in 1939 the well-known maker of sewing machines, the Singer Manufacturing Co., received a “Production Study” contract to develop a manufacturing program for the M1911A1. This was followed on April 17, 1940 by an “Educational Order” contract for 500 M1911A1s. The pistols made by Singer were serially numbered in the S800001 to S800500 range. It was eventually determined that the company could better serve the war effort by concentrating on manufacturing other military equipment. Thus, Singer did not produce any additional .45s for the government beyond the 500 made under the Educational Order.

After Pearl Harbor, the already high demand increased exponentially. On March 16, 1942, the Remington Rand Co. received a government contract for the production of 125,000 M1911A1 pistols to be made at the firm’s Syracuse, New York facility. Some of the machinery and tooling used by Singer to fabricate the 500 Educational Order pistols was sent to Remington Rand. To speed production, the company obtained a number of components from various sources, including Colt, Springfield Armory and High Standard Arms Co. The first Remington Rand pistols were delivered to the government in November 1942. However, production was temporarily halted in March 1943 to correct problems encountered regarding the non-interchangeability of parts. This was eventually corrected and Remington Rand received additional contracts and continued turning out .45 pistols until the end of World War II. The firm made almost 900,000 M1911A1 pistols at the lowest per-unit cost of all the manufacturers.

On May 5, 1942, the Swissvale, Pa., firm of Union Switch & Signal was granted a contract for the manufacture of 200,000 M1911A1s. The firm delivered its first pistols in March 1943, but US&S was unexpectedly informed that its contract would be reduced to just 30,000 so the firm could concentrate instead on the production of M1 carbine parts. Just before these pistols were completed, however, the government ordered an additional 25,000 M1911A1s. Union Switch & Signal completed the last of the 55,000 pistols on Nov. 27, 1943.

In December 1942, the Ithaca Gun Co. began production of M1911A1 pistols. Other than Colt, Ithaca was the only firm that had previously manufactured firearms prior to receiving a contract to produce M1911A1s. As was the case with some of the other manufacturers, Ithaca received a number of components from various sources to expedite production of the pistols. The firm also redesigned some of the parts, such as the trigger and hammer, to speed production and reduce cost. Ithaca manufactured a total of 335,466 M1911A1s.

In addition to the new production guns made by the above firms, large numbers of existing M1911 pistols were issued during World War II. Since the guns had been in service for almost a quarter century, many required refurbishment or overhaul.

The .45 pistol saw widespread service in all theaters of the war and further cemented its already stellar reputation as one of the finest military handguns of all time. The pistol was often criticized for being heavy and, like most handguns, required training and practice to be reasonably proficient while shooting at anything much beyond point-blank range. Regardless, the .45 was reliable and possessed potent short-range “stopping power.” One example of this occurred during an incident on Guadalcanal: “There was a moment of heart-stopping drama at the division [command post] when a sword-wielding Japanese officer stepped into the open with two riflemen and headed directly for Archer Vandegrift, who was in the open, alone and unarmed. Master Gunnery Sergeant Sheffield Banta, an utterly unflappable old salt, stopped typing a report long enough to unholster his .45-caliber automatic pistol and plug the officer dead in his tracks.”

Despite such instances, a handgun was essentially a supplemental sidearm and was generally employed in actual combat action only when the more effective rifles and automatic arms were unavailable, out of ammunition or damaged. An Oct. 23, 1943, Marine Corps document titled “Report on Infantry Weapons in Combat” gave a brief synopsis of the various arms used by a Marine Raider Battalion on New Georgia Island. The section pertaining to the .45 simply stated: “U.S. Pistol, Cal. .45, M1911-M1911A1. Held up very well, but used very little.”

Many .45 pistols were acquired by troops who were not officially authorized to be issued them as called for in their unit’s TOE (Table of Organization and Equipment). However, such regulations were rarely enforced in combat zones, and many G.I.s and Marines who could acquire a .45 did so, and considered themselves lucky.

A leather hip holster, the Model of 1912, was standardized soon after the M1911’s adoption. This holster had a swivel attachment to make it better adapted to cavalry use. Just before America’s entry into World War I, the Model of 1916 holster was adopted, which differed from the M1912 primarily in the deletion of the swivel feature. Both were fitted with wire hooks that attached to the grommets on the bottom of the standard webbed pistol belt or cartridge belt. There were sufficient numbers of World War I-vintage M1916 holsters to meet the demand until the U.S. became actively involved in World War II. The M1916 holster was put back into production and almost 3 million were made by 18 different commercial firms between 1941 and 1945. These holsters were embossed with a large “U.S.” on the cover flap, with the name of the maker and year of production on back.

I have a '43 Rem-Rand that was reworked at RIA in the '60s as a match pistol for most likely the Navy or Marines. Still can win with it.

I carried my Remington Rand .45 from 1968 to 2002 when I replaced it as a duty weapon with a Kimber TLE in .45acp. As range officer for the agency I went on a campaign to do away with the Glock 40 S&W. After 12 years they finally decided John Browning knew what he was talking about and upgraded to the .45acp.

When considering the military in high school I choose the Army for the .45 that was issued to the Military Police over the .38 that was issued to Air Force SP's.

My WWII 1911 Colt with 1942 serial # production shoots as smooth and accurate as it ever did. Same goes for my WWI Springfield. Yes, to answer Richard's question.

I have a non-Military 1911 Remington UMC made in 1918 with a four digit SN. One of 20,000 made by UMC but no military making.

Actually the article was correct. Remington-Rand, maker of the M1911A1 pistol, was not the same entity as Remington Arms Company. Remington-Rand never made guns prior to WWII. Remington Arms made lots of guns for many years.

re: Steelheart. Wrong Remington. Look up Union Cartridge Company.

I think there's a mistake in the article. According to the article Remington didn't make firearms prior to WWII. But Remington's site says that they've been making firearms since 1816. http://www.remington.com/pages/our-company/our-company.aspx Other than that it's a great article. Steelheart

I carry a hi-cap Para-Ordnance P-14 & wouldn't be caught dead without it. What makes guns like these so amazing to me is the fact that John Moses Browning invented this gun over 100 years ago - and it is still, to this day, "THE" gun of choice among firearm experts and firearm devotees over virtually all others out there - most of which are "newer" designs. Browning's original is still the best - JMB was a true genius and light-years ahead of his time!! I also own and still shoot regularly a low 4-digit serial number 1911 that was mfgr'd sometime in 1912, and it still performs flawlessly. What an incredible design these guns are!!

I think it was a big mistake for the US Armed forces to replace the M-1911 with a 9mm which does not have the stopping power of the 45 ACP. I have used a large variety of handguns in law enforcement, and I always went back to Colt 45 as the best choice.
