The Colt New Service Revolver

The Colt New Service Revolver

The Colt New Service was a dominant player in the large-caliber revolver market for four decades. The New Service was loaded by swinging out the cylinder to the left and inserting six cartridges. Pushing in on the ejector rod extracted all six cases at once.

In 1888, Colt employee Carl Ehbets patented a swing-out-cylinder revolver whose cylinder was locked in position by an internal pin that engaged a depression in the center of the rotating ratchet at the rear of the cylinder. The pin was attached to an external latch on the right side of the frame that, when pulled to the rear, disengaged the pin and allowed the cylinder to be swung out to the left where the cartridge cases were ejected by pushing on a rod that passed through the cylinder pin and was attached to a star-shaped ejector. All subsequent Colt swing-out-cylinder revolvers have been based upon that design.

The following year, the U.S. Navy adopted the new Colt revolver chambered for the .38 Long Colt cartridge, and three years later, the Army followed suit. The new Colt .38 revolvers saw their first large-scale combat use during the Spanish-American War (1898), but during the postwar pacification campaign in the Philippines, fighting against the fanatical Muslim Moros showed the shortcomings of the .38 revolver. Juramentado suicide warriors often soaked up multiple .38 projectiles and kept on coming with their kris knives swinging. A more authoritative sidearm was needed, and as it had in the past, the Army looked to Colt.

In 1898, Colt had introduced its first large-caliber, swing-out-cylinder revolver. Called the New Service, it was an up-sized and strengthened variant of the .38 Colt revolver, and it was offered chambered for the popular big-bore revolver cartridges of the day: .38-40, .44-40, .44 Russian, .44 Special, .45 Colt, .450 Boxer (rare), .455 Webley, and .476 Enfield (rare). Options included barrel lengths of 4, 4½, 5, 5½, 6, and 7½ inches; wood or hard rubber grips; and blue or nickel finishes.

The Army purchased several thousand New Service revolvers. Known as the Model of 1909, they were chambered for a variation of the .45 Colt that used a wider rim for more positive ejection. The U.S. Marine Corps obtained a small number that had slightly different shaped grips.

In that same year, Colt improved the New Service's mechanism, replacing a number of leaf springs with coil springs that strengthened the lockwork and reduced parts breakage. The "Colt Positive Lock" was also included in the design. It interposed a steel bar between the hammer and the frame, and that bar prevented the revolver from firing if the hammer was inadvertently released while cocking or if the revolver was dropped on its hammer.

The large-caliber Colt wheelgun proved to be popular with American outdoorsmen and law enforcement. Over the years, the .45-caliber Colt New Service was used by the New York State Police and the highway patrols of Georgia, Utah, and Montana. Michigan State troopers were issued .44-40 New Service revolvers prior to World War I.


The New Service was also popular outside the U.S. Numbers were purchased by British officers for use during the Boer War in South Africa. In 1904, the Royal Canadian Mounted Police adopted the New Service in .455 Webley, and beginning in 1919, they used .45 Colt New Service revolvers. The Cuban government purchased .45 Colt New Services before and after World War I for issue to their army and the Guardia Rurales.

With the outbreak of World War I, the British purchased .455 revolvers from Colt and S&W. As it became obvious that the United States would soon be drawn into the conflict, the Army approached S&W in 1916 about a substitute standard handgun and was offered the .45 Hand Ejector, Second Model revolver. But the Army insisted that any substitute standard handgun had to use the issue pistol cartridge, and the rimless .45 ACP would not function with the S&W revolver's ejector system.

In conjunction with the Springfield Armory, S&W developed the halfmoon clip--a semi-circular piece of flat steel with cutouts into which three rimless .45 ACP cartridges could be snapped. This allowed the rimless cases to be ejected by the extractor bearing on the clip and also facilitated very fast reloading.

When the U.S. declared war on April 2, 1917, S&W began production of the Smith & Wesson Revolver, Caliber .45, Model 1917. While the Colt factory gave priority to the production of Model 1911 pistols, it too received a contract for revolvers, and it proved to be a simple matter to modify the New Service to accept the halfmoon clips and the .45 ACP cartridge. The result was the Colt Revolver, Caliber .45, Model 1917. Early Colt Model 1917s had their chambers bored straight through and could not fire the .45 ACP without benefit of the halfmoon clips, while later production guns had a neck in the chamber to allow them to be fired without clips in an emergency.

The Colt 1917 soon appeared in hands of the Doughboys who found the big Colt a rugged, powerful handgun capable of standing up to the vile conditions of trench warfare. One notable personality who was so equipped was artillery Capt. (later President) Harry S. Truman, who in later years presented his Colt 1917 revolver and 1911 pistol to the NRA's museum.

By 1918, Colt had delivered 151,700 Model 1917s to the government. After the war, except for a few that were retained for use by military police or distributed to National Guard units, most Colt and S&W Model 1917 revolvers were put into storage. During the interwar years, Model 1917s were used by various federal agencies, including the Border Patrol, Post Office, Justice Department, and Treasury Department. The Army, which handled distribution, showed a definite preference for the Colt, and they accounted for the majority issued.

While the factory never used model numbers, today's collectors recognize three versions of the New Service. The Old Model, or the first 21,000 New Services, featured a straight, untapered barrel and a rather unattractively shaped trigger guard. After the Old Model, several thousand Transitional Models (Model of 1909) were produced with a number of mechanical improvements, including a hammer-block safety. The Improved Model started with the Model 1917 and went to the end of production. Its slightly tapered barrel had a larger collar where it screwed into the frame and a

larger, more ergonomic trigger guard.

The postwar years saw the .44 Russian, .450 Boxer, and .476 Enfield chamberings dropped and the .38 Special added. Colt's 1933 catalog opined, "The New Service is essentially a holster revolver for the man in the open-mounted Motorcycle and State Police, the Hunter, Explorer and Pioneer. It is the Arm adopted as standard by the Royal Canadian Mounted Police and hundreds of city and state Police Organizations throughout the world."

The year 1936 saw the New Service chambered for the powerhouse handgun cartridge of the day, the .357 Magnum. The New Service in .38 Special was popular with police and was used by the Texas Dept. of Public Safety, U.S. Border Patrol, Pennsylvania State Police, Kansas Highway Patrol, the Tennessee Valley Authority, and San Antonio and Richmond police departments. The New Hampshire State Police bought some in .357 Mag.

Colt's 1940 catalog offered the New Service with barrel lengths of 4½ , 5½, and 7½ inches with blue or nickel finishes in .38-40, .44 Special, .44-40, .45 Colt, .45 ACP, and .455 Webley. Guns in .38 Special and .357 were offered with 4-, 5-, and 6-inch barrels. While checkered walnut grips were standard, late-production guns were fitted with plastic-like "Coltwood" grips.

With the American entry into World War II, Army warehouses were swept for weapons, and the government located 96,000 plus Model 1917 Colts that were reconditioned and issued to military police and training units. Despite wartime demands, Colt assembled a limited number of New Services from parts on hand, and according to factory figures, a total of approximately 357,000 New Service revolvers were produced by 1944.

Shooting A .38-40 Colt New Service
My brother Vincent arranged for me to borrow a New Service revolver from a friend's collection. Chambered for the .38-40, it was in VG+ condition and featured a 4½-inch barrel and Coltwood grips. According to its serial number, it must have been one of the very last ones assembled in 1944. It had a smooth trigger pull, and unlike most handguns of that era, the sights were prominent, fast to acquire, and easy to line up.

While .38-40 ammo is hard to find nowadays, I obtained a supply of cowboy action loads from Black Hills and Ten-X. Reloading guru and fellow InterMedia Outdoors contributor Bob Shell provided me with one of his favorite loads consisting of a 170-grain JHP bullet backed by 8.5 grains of Unique.

When fired from my MTM Predator rest at 50 feet, the Colt printed a bit low and to the left. Two out of the three loads put bullets close enough to where I was aiming for a fixed-sight, service-type revolver. The revolver showed a slight preference for faster bullets, and as projectile velocity increased, group sizes shrank.

After chronographing the three loads, I set up a D-1 target and ran the New Service through a series of offhand drills from 7 and 15 yards. Here, the big Colt came into its own, and keeping all my rounds in the center of the target was easy. The double-action trigger pull was a bit heavy, but this revolver was in NIB condition, and I believe it had been fired very little, if at all, before I ran it through its paces.

All in all, I was impressed with the New Service. While I am not a real fan of large-frame revolvers, it was reliable, comfortable to shoot, and put rounds where I wanted them to go. And when all the advertising hype is wiped away, what else do you need from a service-type handgun?

The 1944-vinatge New Service in .38-40 that Paul test-fired for this report proved to be pleasingly accurate.
