Colt's Manufacturing Company, LLC (CMC, formerly Colt's Patent Firearms Manufacturing Company) is a United States firearms manufacturer, whose first predecessor corporation was founded in 1836 by Samuel Colt. Colt is best known for the engineering, production, and marketing of firearms over the later half of the 19th and the 20th century. Colt's earliest designs played a major role in the popularization of the revolver and the shift away from earlier single-shot pistols. While Sam Colt did not invent the revolver concept, his designs resulted in the first very successful ones.
The most famous Colt products include the Colt Walker, Single Action Army or Peacemaker, and the Colt Python. John Browning worked for Colt for a time, and came up with a design for a semiautomatic pistol, which debuted as the Colt M1900 pistol and eventually evolved into the Colt M1911 pistol. Though they did not develop it, for a long time Colt was primarily responsible for all AR-15 and M16 rifle production, as well as many derivatives of those firearms. The most successful and famous of these are numerous M16 carbines, including the Colt Commando family, and the M4 carbine.
In 2002, Colt Defense was split off from Colt's Manufacturing Company. Colt Manufacturing Company now serves the civilian market, while Colt Defense serves the law enforcement, military, and private security markets worldwide.
19th century 
Samuel Colt received a British patent on his improved design for a revolver in 1835, and two U.S. patents in 1836, one on February 25 (later numbered U.S. Patent 9430X) and another on August 29 (U.S. Patent 1,304). That same year, he founded his first corporation for its manufacture, the Patent Arms Manufacturing Company of Paterson, New Jersey, Colt's Patent. This corporation suffered quality problems in production. Making firearms with interchangeable parts was still rather new (it had reached commercial viability only about a decade before), and it was not yet easy to replicate across different factories. Interchangeability was not complete in the Paterson works, and traditional gunsmithing techniques did not fill the gap entirely there. The Colt Paterson revolver found patchy success and failure; some worked well, while others had problems. The United States Marine Corps and United States Army reported quality problems with these earliest Colt revolvers. Production had ended at the New Jersey corporation by 1842.
Colt made another attempt at revolver production in 1846 and submitted a prototype to the US government. During the Mexican–American War (1846–1848), this prototype was seen by Captain Samuel Hamilton Walker who made some suggestions to Colt about making it in a larger caliber. Having no factory or machinery to produce the pistols, Samuel Colt collaborated with the Whitney armory of Whitneyville, Connecticut. This armory was run by the family of Eli Whitney. Eli Whitney Jr (born 1820), the son of the cotton-gin-developer patriarch, was the head of the family armory and a successful arms maker and innovator of the era. Colt used a combination of renting the Whitney firm's facilities and subcontracting parts to the firm to continue his pursuit of revolver manufacture.
Colt's new revolvers found favor with Texan volunteers (the progenitors of later Texas Rangers cavalry groups), and they placed an order for 1,000 revolvers that became known as the Colt Walker, ensuring Colt's continuance in manufacturing revolvers. In 1848, Colt was able to start again with a new corporation of his own. He founded the Colt's Patent Firearms Manufacturing Company in Hartford, Connecticut.
Colt purchased a large tract of land beside the Connecticut River, where he built his first factory in 1848, a larger factory called the Colt Armory in 1855, a manor that he called Armsmear in 1856, and employee tenemant housing. He established a ten-hour day for employees, installed washing stations in the factory, mandated a one-hour lunch break, and built the Charter Oak Hall, a club where employees could enjoy games, newspapers, and discussion rooms. Colt ran his plant with a military-like discipline, he would fire workers for tardiness, sub-par work or even suggesting improvements to his designs.
In an attempt to attract skilled German workers to his plant, Colt built a village near the factory away from the tenemants which he named Coltsville and modeled the homes after a village in Pottsdam. In an effort to stem the flooding from the river he planted German osiers, a type of willow tree in a 2-mile long dike. He subsequently built a factory to manufacture wicker furniture made from these trees.
The 1850s were a decade of phenomenal success for the new Colt corporation. Colt was the first to widely commercialize the total use of interchangeable parts throughout a product. It was a leader in assembly line practice. It was a major innovator and training ground in manufacturing technology in this decade (and several after). Soon after establishing his Hartford factory, Colt set out to establish a factory in Europe and chose London, England. He organized a large display of his firearms at the Great Exhibition of 1851 at Hyde Park, London and ingratiated himself by presenting cased engraved Colt revolvers to such appropriate officials as Britain’s Master General of the Ordnance. At one exhibit Colt disassembled ten guns and reassembled ten guns using different parts from different guns. As the world’s leading proponent of mass production techniques, Colt went on to deliver a lecture on the subject to the Institute of Civil Engineers in London. The membership rewarded his efforts by awarding him the Telford Gold Medal.
Colt's presence in the British market caused years of acrimony and lawsuits among British arms makers, who doubted the validity of Colt's British patent and the desirability of the American system of manufacturing. It took many more years and a UK government commission before the point became universally accepted that such manufacture was possible and economical. Colt opened his London plant on the River Thames at Pimlico and began production on January 1, 1853. Many English people saw Colt’s advanced steampowered machinery as proof of America’s growing position as a leader in modern industrial production. On a tour of the factory, Charles Dickens was so impressed with the facilities that he recorded his favorable comments of Colt's revolvers in an 1852 edition of Household Words. Most significant, the Colt factory’s machines mass-produced interchangeable parts that could be easily and cheaply put together on assembly lines using standardized patterns and gauges by unskilled labor as opposed to England's top gunmakers.
In 1854 the British Admiralty ordered 4,000 Navy Model Colt revolvers. In 1855 the British Army placed an order for 5,000 of these revolvers for army issue. Despite a following order later in the year for an additional 9,000 revolvers, Colt failed to convince the British to adopt his revolver as the issue sidearm for the army. Colt began to realize that British sales were failing to meet his expectations. Unable to justify the London factory’s expenses, Colt closed the London factory in 1856. Over the next few months his workmen crated and shipped the machinery and unassembled firearms back to America.
Though the U.S. was not directly involved in the Crimean War (1854–1856), Colt's weapons were used by both sides. In 1855 Colt unveiled new state-of-the-art armories in the Hartford and London factories stocked with the latest machine tools (some of which were of Colt's devising), many built by Francis A. Pratt and Amos Whitney, who would found the original Pratt & Whitney toolbuilding firm a few years later. For example, the Lincoln miller debuted to industry at these armories.
Colt had set up libraries and educational programs within the plants for his employees. Colt's armories in Hartford were seminal training grounds for several generations of toolmakers and other machinists, who had great influence in other manufacturing efforts of the next half century. Prominent examples included F. Pratt and A. Whitney (as mentioned above); Henry Leland (who would end up at Cadillac and Lincoln); Edward Bullard Sr of the Bullard firm; and, through Pratt & Whitney, Worcester R. Warner and Ambrose Swasey (of Warner & Swasey).
In 1852 an employee of Colt's, Rollin White, came up with the idea of having the revolver cylinder bored through to accept metallic cartridges. He took this idea to Colt who flatly rejected it and ended up firing White within a few years. Colt historian RL Wilson has described this as the major blunder of Sam Colt's professional life. Rollin White left Colt's in December 1854 and registered a patent on April 3, 1855 in Hartford, Connecticut, as patent number 12,648: Improvement in Repeating Fire-arms. On November 17, 1856 White signed an agreement with Smith & Wesson for the exclusive use of his patent. The contract stipulated that White would be paid 25 cents for every revolver, but that it was up to him to defend his patent against infringement as opposed to Smith & Wesson.
During the 1850s and 1860s, Rollin White had been permanently trying to keep control on his breech-loading system patent, bringing a lawsuit to any breech-loaded manufactured gun. He nevertheless obtained an advance against royalties for using his patent from Smith & Wesson, a company that not only introduced its first revolver in 1857 (Smith & Wesson Model 1, a rear-loader) but also started, as of 1858, to convert cap & ball percussion guns into rear-loaders, even with formerly Colt manufactured revolvers. But the Colt's company itself was prevented by American laws from infringing the Rollin White patent and all along the 1850s and 1860s continued manufacturing percussion guns. In 1860 it produced a new revolver model for the United States Army. This Colt Army Model 1860 appeared just in time for the American Civil War.
1860–1865: American Civil War 
The American Civil War was a boon to firearms manufacturers such as Colt's, and the company thrived during the conflict. Sam Colt had carefully developed contacts within the ordnance department signing the very first government contract for 25,000 rifles. Colt's Factory was described as "an industrial palace topped by a blue dome" and powered by a 250-horsepower steam engine. During the American Civil War Colt had 1,500 employees who produced 150,000 muskets and pistols a year. In 1861 and 1863 the company sold 107,000 of the Colt Army Model 1860, alone, with production reaching 200,500 by the end of the war in 1865.
During the war, Colt's was still prevented by the American laws from infringing the Rollin White's patent rights. Nevertheless the war made a huge fortune for the company, allowing Sam Colt to become America's first manufacturing tycoon, but he did not live to see the end of it. He died of rheumatic fever on January 10, 1862, and his close friend and firearms engineer, Elisha K. Root, took over as Colt's company president. On February 4, 1864 a fire destroyed most of the factory including arms, machinery, plans, and factory records. On September1, 1865 Root died leaving the company in the hands of Samuel Colt's brother-in-law, Richard Jarvis. The company's Vice-president was William B. Franklin, who recently left the Army at the end of the Civil War. With the Civil War over and no new military contracts Colt's Manufacturing had to lay off over 800 employees.
The company found itself in a precarious situation, the original revolver patents had expired and other companies could produce copies of his designs. Additionally, metallic cartridge revolvers had been gaining in popularity, but Colt could not produce any because of the Rollin White patent held by rival, Smith & Wesson. Likewise, Colt had been so protective of its own patents that other companies were unable to make revolvers similar to their design. As the Rollin White patent was nearing expiration, Colt moved toward developing a metallic cartridge revolver.
1865–1880s: Post–Civil War 
Colt's first effort toward a metallic cartridge revolver was by conversion of existing percussion revolvers. The first of these conversions was patented on September 15, 1868 by Colt engineer, F. Alexander Thuer as patent number 82258. The Thuer conversion was made by milling off the rear of the receiver and replacing it with a breechplate containing six internal firing pins. The cartridges were loaded through the mouths of the chambers. Colt made 5000 of these but they were not well accepted. Colt found the mechanism so complex it included a spare percussion cylinder with each revolver.
Colt tasked its superintendent of engineering, Charles Richards, to come up with a solution. The Richards conversion was performed on the Colt 1860 Army revolver. The caliber was .44 Colt and the loading lever was replaced by an ejector rod. This conversion added a breechplate with a firing pin and a rear sight mounted on the breechplate. Cartridges were loaded into the cylinder one at a time via a loading gate. Colt manufactured 9000 of these revolvers between 1873 and 1878. In 1873, Colt performed the same conversion on the M1851 and M1861 revolvers for the US Navy in .38 rimfire. Another of Colt's engineers, William Mason, improved this conversion by placing the rear sight on the hammer and, along with Richards, he was granted patents in 1871 to convert percussion revolvers into rear-loading metallic-cartridge revolvers. Those converted revolvers are identified as the "Richards-Mason conversion". There were approximately 2100 Richards-Mason M1860 Army conversions made from 1877 to 1878 in a serial-number range 5800 to 7900.
In November 1865, Franklin had attempted to purchase a license to the Rollin White patent from competitor Smith & Wesson. White and Smith & Wesson would take no less than $1.1 million, but Franklin and Colt's directors decided it was too large an investment on a patent that would expire in 1868. In the meantime, Colt turned its attention to manufacturing goods other than firearms, such as watches, sewing machines, typewriters and bicycles. In 1868 Rollin White requested an extension to his patent, but the request was rejected. He then turned to the Congress, but the request was again rejected, this time by the Senate and on the initiative of President Ulysses Grant, in January 1870. This lead the patent to expire, allowing competitors to develop their own breech-loading guns and metallic cartridges. Following this, on that same year of 1870, Colt's bought the National Arms Company, a Brooklyn, New York company known for manufacturing derringers and for circumventing the Rollin White patent by utilizing a unique cartridge. Colt continued to produce the .41 Rimfire derringer after the acquisition, as an effort to help break into the metallic-cartridge gun market, but also introduced its own three Colt Derringer Models, all of them also chambered with a .41 Rimfire unique cartridge. The last model to be in production, the third Colt Derringer, was not droped until 1912. The first metallic cartridge breech-loading weapons sold by Colt's where then those Derringers, as of 1870, formerly conceived by the National Arms Company, but Colt's also started developing its own rear-loading guns and cartridges.
In 1871 Colt's introduced its first revolver models using rear-loaded metallic cartridges: the .41 caliber Colt House Revolver (also known as the Cloverleaf under its four-round cylinder configuration) and the .22 cal Colt Open Top Pocket Model Revolver. But Colt's wanted a more powerful practical hanggun loaded with metallic cartridges so the company put forward William Mason, who in 1871 began work on Colt's first .44 caliber metallic-cartridge revolver: the Colt Model 1871-72 Open Top. The company registered two patents for the Open Top, one in 1871, the other in 1872, the same patents mentioned in the markings of Colt Single Action Army revolvers, a nowadays legendary and long produced model, improved and based on the Open Top. Production of the Open Top started in 1872 and stoped in 1873 when the Single Action Army model started to be delivered to the US Army. But the Open Top was already a completely new design. The parts, for example, would not interchange with the older percussion pistols. Mason moved the rear sight to the rear of the barrel as opposed to the hammer or the breechblock of the earlier efforts. The caliber was .44 rimfire and it was submitted to the US Army for testing in 1872. The Army rejected the pistol and asked for a more powerful caliber with a stronger frame. Mason redesigned the frame to incorporate a topstrap, similar to the Remington revolvers, and placed the rear sight on the rear of the frame; he consulted with Richards on some other improvements. The first prototype of the new gun was still chambered in .44 rimfire, but the first model was in the newest caliber known as the .45 Colt. The revolver was chosen by the Army in 1872, with the first order, for 8000 revolvers, shipping in the summer of 1873: The Colt Single Action Army or "Peacemaker", also known as the Colt Model 1873, was born. This revolver was one of the most prevalent firearms in the American West during the end of the 19th century and Colt still produces it, in six different calibers, two finishes and three barrel lengths.
In the new market of metallic cartridge rear-loading pocket revolvers, Colt's not only introduced its three Derringer Models (as of 1870) or the Colt House and the Open Top Pocket (the last two as of 1871) but also introduced in 1873 a subsequent design called its “New Line” revolver models, based on William Mason's patents.
After the success of the Colt Single Action Army and Colt's conversion of existing percussion revolvers to Richards-Mason conversions, Mason went on to design Colt's first Double-action revolver, the Colt M1877. Following this, he once again teamed up with Richards to produce a larger-framed version, the Colt M1878 Frontier. It was Colt's first large-frame, double-action revolver. It combined the front end of the Single Action Army revolver with a double-action, 6-shot frame mechanism. It was available commercially in numerous calibers.
The 1870s and 1880s provided sales opportunity to the Colt company via the spread of European-American society ever further westward across the continent, and the demand for firearms that it engendered in various ways. As white Americans displaced Indians from the Indian Territory, both sides were eager for firearms. On the white side, both the U.S. Army and civilians were customers of Colt. The Army carried Colt revolvers through the last of its Indian Wars. On the Indian side, Colt weapons were captured when possible, or bought from whoever was selling. Even among whites in towns where Indians had been vanquished, a thriving demand for guns existed, from the criminals to the police to self-defending civilians. Memoirs of Americans including Walter Chrysler and Jack Black speak of what it was like growing up in Western towns where most people had guns and open carry was common (such as in Kansas and Missouri, which were considered "out West" at the time—now considered the Old West).
Colt finally left the "loading gate concept" for a swing-out cylinder on its revolvers with the Colt M1889 Navy revolver, which resembled the Colt M1878 and was based on another design by Mason. The model was produced for three years between 1889 and 1892, and eclipsed by the Colt M1892 chambered in .38 Long Colt. The M1892 was replaced by the New Service Double Action revolver in 1899. In caliber .45 Colt, the New Service was accepted by the U.S. Military as the Model 1909 .45 revolver. The New Service revolver was available in other calibers such as .38 Special and, later in the 20th century, .45 ACP (as the M1917 revolver) and .357 Magnum.
Under a contract with the U.S. Army, Colt Arms built the Model 1895 ten-barrel variant of the Gatling Gun, capable of firing 800-900 .30 Army rounds per minute, and used with great effect at the Battle of San Juan Hill. The M1895 Colt-Browning machine gun or "Potato Digger" was built by Colt. The Colt-Browning was one of the first gas-operated machine guns, originally invented by John Browning. It became the first automatic machine gun adopted by the United States and saw limited use by the U.S. Marine Corps at the invasion of Guantánamo Bay and by the 1st Volunteer Infantry in the Santiago campaign during the Spanish-American War. In 1901, Elizabeth Jarvis Colt sold the company to a group of outside investors based in New York and Boston.
20th century 
During World War I, Colt surpassed all previous production achievements. Prior to America's entry into the war, orders from Canada and the United Kingdom swelled the backlog of orders to three years. Colt hired 4,000 more workers, making a total of 10,000 employees—and its stock's price increased by 400%. By 1918, Colt had produced and sold 425,500 of the famous John Browning-designed M1911. Because the factory could not keep up with demand for this pistol, the US Military decided to accept Colt New Service revolvers in caliber .45 ACP, called the M1917 revolver, as a substitute weapon. Competing manufacturer Smith & Wesson made double-action revolvers in .45 ACP, which were accepted and issued by the U.S. military under the same name. Colt produced 151,700 revolvers during the war as well as 13,000 Maxim-Vickers machine guns and 10,000 Browning machine guns with an additional 100,000 under subcontract to other companies. Since Auto Ordnance had no tooling for production, Colt acquired the license for the Thompson 1921 SMG and made 15,000 units in the first production year.
The stock market crash of 1929 and the ensuing Great Depression resulted in a slowing down of production for Colt. In anticipation of this, company presidents William Skinner[disambiguation needed] and Samuel Stone implemented a diversification program similar to that done at the close of the American Civil War. Colt acquired contracts for business machines, calculators, dishwashers, motorcycles, and automobiles; all marketed under a name other than Colt. Samuel Stone acquired a firm which manufactured plastics and renamed it "Colt rock" as well as a company that manufactured electrical products. Colt weathered the financial crises of the time by cutting the work week, reducing salaries, and keeping more employees on the payroll than they needed. These measures kept the company in business but ate up the cash surplus they had acquired during the World War I years.
1930s: Great Depression 
In 1935, after employees voted to disband a labor union, 1,000 workers went on strike for 13 weeks. Strikers became violent, attacking workers and detonating a bomb in front of company president Samuel M. Stone's house. The company set up a barracks, dining room, and recreation room for workers within the Colt Armory during the strike. On June 3, 1935 the National Recovery Administration ruled that the company was within its rights not to deal with the union and the strike ended. In the year following the strike, the factory was hit by a hurricane and flood. Many company shipping records and historical documents were lost as a result.
1939–1945: World War II 
At the beginning of World War II, Colt ceased production of the Single Action Army revolver to devote more time to filling orders for the war. During the war Colt manufactured over 629,000 M1911A1 pistols as well as a large number of M1917 water-cooled machineguns. The company had a workforce of 15,000 men and women in three factories and production ran on three shifts, 24 hours a day, and won the Army-Navy rating of "E" for excellence. Colt ranked 99th among United States corporations in the value of World War II military production contracts. However, the company was losing money every year due to mismanagement, an embittered workforce that had been stretched to its limits, and manufacturing methods which were becoming obsolete.
As the war ended and demand for military arms came to a halt, production literally ceased. Many long-time workers and engineers retired from the company and nothing was built from 1945 to 1947. Mismanagement of funds during the war had a serious impact as the 105-year-old firm faced possible bankruptcy. In September 1955 the board of directors voted to merge Colt with an upstart conglomerate called Penn-Texas, which had acquired Pratt & Whitney Machine Tool the same year. Also in 1955, Colt released one of the most famous revolvers in history, the Colt Python. In 1958 Penn-Texas merged with Fairbanks-Morse to form the Fairbanks-Whitney Corporation and in 1964 the conglomerate reorganized as Colt Industries. In 1956 Colt resumed production of the Single Action Army revolver and in 1961 began making commemorative versions of their classic models.
The 1960s were boom years for Colt with the escalation of the Vietnam War, Robert McNamara shutting down the Springfield Armory, and the U.S. Army's subsequent adoption of the M16, for which Colt held the production rights and would sell over 5 million units worldwide. Colt would capitalize on this with a range of AR-15 derivative carbines. They developed AR-15-based Squad Automatic Weapons, and the Colt SCAMP, an early PDW design. The Colt XM148 grenade launcher was created by Colt's design project engineer, gun designer Karl R. Lewis. The May 1967 "Colt's Ink" newsletter announced that he had won a national competition for his selection and treatment of materials in the design. The newsletter stated in part "In only 47 days, he wrote the specifications, designed the launcher, drew all the original prints, and had a working model built". At the end of the 1970s, there was a program run by the Air Force to replace the M1911A1. The Beretta 92S won, but this was contested by the Army. The Army ran their own trials, leading eventually to the Beretta 92F being selected as the M9.
The 1980s were fairly good years for Colt, but the coming end of the Cold War would change all that. Colt had long left innovation in civilian firearms to their competitors, feeling that the handgun business could survive on their traditional revolver and M1911 designs. Instead, Colt focused on the military market, where they held the primary contracts for production of rifles for the US military. This strategy dramatically failed for Colt through a series of events in the 1980s. In 1984, the U.S. military standardized on the Beretta 92F. This was not much of a loss for Colt's current business, as M1911A1 production had stopped in 1945. Meanwhile, the military rifle business was growing because the U.S. military had a major demand for more upgraded M16s, the M16A2 model had just been adopted and the Military needed hundreds of thousands of them.
In 1985, Colt's workers, members of the United Auto Workers went on strike for higher wages. This strike would ultimately last for five years, and was one of the longest running labor strikes in American history. With replacement workers running production, the quality of Colt's firearms began to decline. Dissatisfied with Colt's production, in 1988 the U.S. military awarded the contract for future M16 production to Fabrique Nationale.
Some criticized Colt's range of handgun products in the late 1980s as out of touch with the demands of the market, and their once-vaunted reputation for quality had suffered during the UAW strike. Colt's stable of double-action revolvers and single-action pistols was seen as old-fashioned by a marketplace that was captivated by the new generation of "wondernines" - high-capacity, 9x19mm Parabellum caliber handguns, as typified by the Glock 17. Realizing that the future of the company was at stake, labor and management agreed to end the strike in an arrangement that resulted in Colt being sold to a group of private investors, the State of Connecticut, and the UAW itself.
The new Colt first attempted to address some of the demands of the market with the production in 1989 of the Double Eagle, a double-action pistol heavily based on the M1911 design, which was seen as an attempt to "modernize" the classic Browning design. Colt followed this up in 1992 with the Colt All American 2000, which was unlike any other handgun Colt had produced before—being a polymer-framed, rotary-bolt, 9x19mm handgun with a magazine capacity of 15 rounds. It was designed by Reed Knight, with parts manufactured by outside vendors and assembled by Colt; its execution was disastrous. Early models were plagued with inaccuracy and unreliability, and suffered from the poor publicity of a product recall. The product launch failed and production of the All American 2000 ended in 1994. This series of events led to the company's Chapter 11 bankruptcy in 1992.
The 1990s brought the end of Cold War, which resulted in a large down turn for the entire defense industry. Colt was hit by this downturn, though it would be made worse later in the 1990s by a boycott by the shooting public in America. In 1994, the assets of Colt were purchased by Zilkha & Co, a financial group owned by Donald Zilkha. It was speculated that Zilkha's financial backing of the company enabled Colt to begin winning back military contracts. In fact during the time period it won only one contract, the M4 carbine. However, the U.S. Military had been purchasing Colt Carbines for the past 30 years (See Colt Commando). During a 1998 Washington Post interview, CEO Ron Stewart stated that he would favor a federal permit system with training and testing for gun ownership. This led to a massive grass-roots boycott of Colt's products by gun stores and US gun owners.
Zilkha replaced Stewart with Steven Sliwa and focused the remainder of Colt's handgun design efforts into "smart guns," a concept favored politically, but that had little interest or support among handgun owners or Police Departments. This research never produced any meaningful results due to the limited technology at the time. Colt announced the termination of its production of double action revolvers in October 1999.
21st century 
The boycott of Colt gradually faded out after William M. Keys, a retired U.S. Marine Lt. General, took the helm of the company in 2002. Keys salvaged Colt's reputation and brought Colt from the brink of bankruptcy to an international leader in Defense production. In 2010 Gerald R. Dinkel replaced Keys as CEO of Colt Defense LLC, while Keys remained on the Board of Directors for Colt Defense.
Colt has to compete with other companies that make M1911-style pistols such as Kimber and AR-15 rifles such as Bushmaster. Bushmaster has subsequently overtaken Colt in the number of AR-15s sold on the civilian market. Colt suffered a legal defeat in court when it sued Bushmaster for trademark infringement claiming that "M4" was a trademark that it owned. The judge ruled that since the term M4 is a generic designation that Colt does not specifically own, Colt had to pay monetary reimbursement to Bushmaster to recoup Bushmaster's legal fees. The M4 designation itself comes from the U.S. military designation system, whose terms are in the public domain.
Colt has entered in several US contracts with mixed results. For example, Colt had an entry in the Advanced Combat Rifle (ACR) program of the 1980s, but along with other contestants failed to replace the M16A2. Colt and many other makers entered the US trials for a new pistol in the 1980s, though the Beretta entry would win and become the M9 Pistol. The Colt OHWS handgun was beaten by H&K for what became the MK23 SOCOM, it was lighter than the H&K entry but lost in performance. Colt did not get to compete for the XM8 since it was not an open competition. Colt is a likely entrant in any competition for a new US service rifle. Current M16 rifles have been made primarily by FN USA since 1988. However, Colt remains the sole source for M4 carbines for the US military. Under their license agreement with Colt, the US military could not legally award second-source production contracts for the M4 until July 1, 2009.

- There is a very well known scene, for example, in the film The Good, the Bad and the Ugly where Blondie (played by Clint Eastwood) loads a breech-loading Colt 1851 Navy Revolver. The film is set in 1862, during the American Civil War, but this is not an anachronism since the Smith & Wesson metallic cartridge conversion of the Navy or other Colt revolvers did indeed exist all along the American Civil War.
