The Founders had been nicely conscious of continuing advances in arms technologies

Throughout the 19th century, firearms enhanced extra than in any other century. As of 1800, most firearms had been single-shot muzzleloading blackpowder flintlocks. By finish of the century, semiautomatic pistols employing detachable magazines with modern day gunpowder and metallic cartridges had been offered. Would the Founders be shocked by the improvements in capability to physical exercise Second Amendment rights? Possibly not, offered the tremendous advances in firearms that had taken location ahead of 1791. And undoubtedly not, offered that James Madison, author of the Second Amendment, initiated a federal government industrial with the distinct aim of vastly enhancing the excellent and quantity of firearms manufacture.

Component I of this post briefly describes Some of the firearms advances ahead of 1791. Component II describes the federal industrial policy for advancing firearms technologies.

This post is primarily based on my report The History of Bans on Forms of Arms Prior to 1900. It is forthcoming in Notre Dame’s Journal of Legislation, vol. 50, no. two, in 2024. The Post also draws on chapter 23 of my coauthored textbook Firearms Law and the Second Amendment: Regulations, Rights, and Policy (Aspen Pub., 3d ed. 2022).

I. Firearms improvements ahead of 1791

Though the Founders could not foresee all the distinct advances that would take location in the nineteenth century, the Founders had been nicely conscious that firearms had been finding much better and much better.

Tremendous improvements in firearms had constantly been portion of the American practical experience. The initially European settlers in America had mostly owned matchlocks. When the trigger is pressed, a smoldering hemp cord is lowered to the firing pan the powder in the pan then ignites the principal gunpowder charge in the barrel.

The initially firearm extra trustworthy than the matchlock was the wheel lock, invented by Leonardo da Vinci. In a wheel lock, the powder in the firing pan is ignited when a serrated wheel strikes a piece of iron pyrite. The wheel lock was the initially firearm that could be kept loaded and prepared for use in a sudden emergency. Despite the fact that matchlock pistols had existed, the wheel lock produced pistols far extra sensible and popular. Paul Lockhart, Firepower: How Weapons Shaped Warfare 80 (2021).

The wheel lock was the “preferred firearm for cavalry” in the sixteenth and seventeenth centuries. Id. The proliferation of wheel locks in Europe in the sixteenth century coincided with the homicide price falling by half. See Carlisle E. Moody, Firearms and the Decline of Violence in Europe: 1200-2010, 9 Rev. Eur. Stud. 53 (2017)

On the other hand, wheel locks expense about 4 instances as considerably as matchlock. Furthermore, their moving components had been far extra difficult than the matchlocks’. Beneath circumstances of difficult use in North America, wheel locks had been also delicate and also tricky to repair. The path of technological advancement frequently entails high-priced inventions sooner or later top to items that are cost-effective to typical buyers and are even much better than the original invention. That has been the story of firearms in America.

Flintlocks quintuple the price of fire

The gun that was even much better than the wheel lock, but easier and much less high-priced, was the flintlock. The earliest versions of flintlocks had appeared in the mid-sixteenth century. But not till the finish of the seventeenth century did most European armies replace their matchlocks with flintlocks. Americans, individually, produced the transition considerably sooner. Lockhart at 106.

Indian warfare in the thick woods of the Atlantic seaboard was primarily based on ambush, rapid raids, and quick person selection-generating in combat—the opposite of the extra orderly battles and sieges of European warfare. In America, the flintlock became a necessity.

As opposed to matchlocks, flintlocks can be kept constantly prepared. Mainly because blackpowder is hygroscopic, and could be ruined by considerably water, it was popular to shop a firearm on the mantel above the fireplace. Yet another benefit, which mattered considerably in America but was mainly irrelevant for European warfare, is that a flintlock, in contrast to a matchlock, has s no smoldering hemp cord to give away the place of the user. Flintlocks are extra trustworthy than matchlocks—all the extra so in adverse climate, despite the fact that nevertheless far from impervious to rain and moisture. Drastically, Flintlocks are considerably easier and more quickly to reload than matchlocks. See, e.g., W.W. Greener, The Gun and Its Improvement 66-67 (9th ed. 1910) Charles C. Carlton, This Seat of Mars: War and the British Isles 1585-1746, at 171-73 (2011).

Initially, the flintlock could not shoot additional or extra accurately than a matchlock. Lockhart at 105. But it could shoot considerably extra quickly. A matchlock requires extra than a minute to reload after. Id. at 107. In seasoned hands, a flintlock could be fired and reloaded 5 instances in a minute, despite the fact that below the anxiety of combat, 3 instances a minute was a extra common price. Id. at 107-08. Compared to a matchlock, a flintlock was extra most likely to ignite the gunpowder charge instantaneously, rather than with a delay of some seconds. Id. at 104. “The flintlock gave infantry the capability to produce an overwhelmingly larger level of firepower.” Id. at 107.

The Theoretical Lethality Index (TLI) is a measure of a weapon’s effectiveness in military combat. The TLI of a seventeenth century musket is 19 and the TLI of an eighteenth century flintlock is 43. Trevor Dupuy, The Evolution of Weapons and Warfare 92 (1984). So the transition of firearm kind in the American colonies extra than doubled the TLI. There is no explanation to think that the American Founders had been ignorant of how considerably much better their personal firearms had been compared to these of the early colonists.

Joseph Belton’s 16-shot model

In 1777 in Philadelphia, inventor Joseph Belton demonstrated a firearm that could fire 16 shots all at after. The committee watching the demonstration integrated Common Horatio Gates, Common Benedict Arnold, and scientist David Rittenhouse. They wrote to the Continental Congress and urged the adoption of Belton guns for the Continental Army. Congress voted to order a hundred–while requesting that they be created as eight-shot models, because gunpowder was scarce. On the other hand, the deal fell by means of simply because Congress could not afford the higher price tag that Belton demanded. Repeating arms had been high-priced, simply because their compact internal elements call for specially complicated and precise fitting.

Therefore, the Founders who served in the Second Continental Congress had been nicely conscious that a 16-shot gun had been created, and was doable to make in quantity, for a higher price tag. Delegates to the 1777 Continental Congress included  future Supreme Court Chief Justice Samuel Chase, John Adams, Samuel Adams, Francis Dana, Elbridge Gerry, John Hancock, the two Charles Carrolls from Maryland, John Witherspoon (President of Princeton, the good American college for totally free believed), Benjamin Harrison (father and grandfather of two Presidents), Francis Lightfoot Lee, and Richard Henry Lee .

The Girardoni rifle

Likewise, the 22-shot Girardoni rifle famously carried by the Lewis &amp Clark expedition beginning in 1803 was no secret, as it had been invented in 1779. It was made use of by the Austrian army as a sniper rifle. Powered by compressed air, its bullet his as difficult as the modern day Colt .45ACP cartridge. John Paul Jarvis, The Girandoni Air Rifle: Deadly Beneath Stress,, Mar. 15, 2011.

The Girardoni had a 21 or 22 round caliber tubular magazine, and could be swiftly reloaded with 20 extra rounds, employing speedloading tubes that came with the gun. Right after about 40 shots, the air reservoir could be exhausted, and would require to be pumped up once more.

Repeaters in ordinary commerce

As of 1785, South Carolina gunsmith James Ransier of Charleston, South Carolina, was marketing 4-shot repeaters for sale. Columbian Herald (Charleston), Oct. 26, 1785.

The American Rifle

The founding generation was specially conscious of one particular of the most popular firearms of their time, the Pennsylvania-Kentucky rifle, which is also known as “The American Rifle.” The rifle was invented by German and Swiss gunsmith immigrants in the early eighteenth century. When they came to Pennsylvania for religious freedom, they had been familiar with the heavy Jaeger rifles of Central Europe.

The American Rifle was developed initially for the desires of frontiersmen who may well invest months on a hunting expedition in the dense American woods. “What Americans demanded of their gunsmiths seemed not possible”: a rifle that weighed ten pounds or much less, for which a month of ammunition would weigh one particular to 3 pounds, “with proportionately compact quantities of powder, be quick to load,” and “with such velocity and flat trajectories that one particular fixed rear sight would serve as nicely at fifty yards as at 3 hundred, the required but slight distinction in elevation becoming supplied by the user’s practical experience.” Robert Held, The Age of Firearms: A Pictorial History 142 (1956). “By about 1735 the not possible had taken shape” with the creation of the iconic American Rifle. Id.

As for the most popular American firearm, the smoothbore (nonrifled) flintlock musket, there had also been good advances. To a casual observer, a fundamental flintlock musket of 1790 appears really equivalent to flintlock musket of 1690. On the other hand, improvements in compact components, some of them internal, had produced the ideal flintlocks far superior to their ancestors. For instance, thanks to English gunsmith Henry Nock’s 1787 patented flintlock breech, “the gun shot so difficult and so quick that the really possibility of such efficiency had hitherto not even been imaginable.” Id. at 137.

The Founders had been nicely conscious that what had been not possible or unimaginable to one particular generation could turn into commonplace in the subsequent. With the federal armories sophisticated investigation and improvement system that started in the Madison administration, the U.S. government did its ideal to make the not possible doable.

II. James Madison and James Monroe, the founding fathers of modern day firearms

U.S. Representative James Madison is nicely-identified as the author of the Second Amendment and the rest of the Bill of Rights. What is not nicely-identified is how his presidency place the United States on the path to mass production of higher-excellent cost-effective firearms.

Mainly because of weapons procurement troubles throughout the War of 1812, President Madison’s Secretary of War James Monroe, who would succeed Madison as President, proposed a system for sophisticated weapons investigation and production at the federal armories, which had been positioned in Springfield, Massachusetts, and Harpers Ferry, Virginia. The Madison-Monroe system was to subsidize technological innovation. Ross Thomson, Structures of  Adjust in the Mechanical Age: Technological Innovation in the United States 1790-1865, at 54-59 (2009). It was enthusiastically adopted with the help of each the significant parties in Congress: the Madison-Monroe Democratic-Republicans, and the opposition Federalists. eight Stat. 204 (1815)  Johnson, Kopel, Mocsary, Wallace &amp Kilmer, Firearms Law and the Second Amendment: Regulation, Rights, and Policy 2209 (3d ed. 2022) (on the internet chapter 23). 

Though serving as ambassador to France, Thomas Jefferson had observed the progress that the French had been generating in creating firearms with interchangeable components. He enthusiastically suggested that the United States do the exact same. See Letter from Thomas Jefferson to John Jay (Secretary of Foreign Affairs below the Confederation government), Aug. 30, 1785, in 1 Memoirs, Correspondence, and Private Papers, of Thomas Jefferson 299 (Thomas Jefferson Randolph ed., 1829). In 1801, President Jefferson recounted his French observations to Virginia Governor James Monroe and expressed hope for Eli Whitney’s strategy for interchangeable gun components. Letter from Thomas Jefferson to James Monroe, Nov. 14, 1801, in 35 The Papers Of Thomas Jefferson 662 (Barbara B. Oberg ed., 2008).

Beneath the bipartisan Madison-Monroe system, generous federal arms procurement contracts had lengthy lead instances and produced considerably of the payment up-front, so that makers could invest various years setting up and perfecting their factories. The system succeeded beyond expectations, and helped to produce the American industrial revolution.

The initial objective was interchangeability, so that firearms components broken in combat could be replaced by functional spare components. Right after that would come larger prices of factory production. And soon after that, it was hoped, production at decrease expense than artisanal production. Attaining these objectives for the extra intricate and closer-fitting components of repeating firearms would be even extra tricky.

To carry out the federal system, the inventors connected with the federal armories initially had to invent machine tools. Contemplate for instance, the wooden stock of a lengthy gun. The back of the stock is held against the user’s shoulder. The middle of the stock is exactly where the action is attached. (The action is the portion of the gun containing the moving components that fire the ammunition the Founding generation known as it “the lock.”) For a lot of guns, the forward portion of the stock would include a groove to hold the barrel.

Creating a stock needs a lot of unique cuts of wood, handful of of them straight. The
artisanal gunmaker would reduce with hand tools such as saws and chisels. Necessarily, one particular artisanal stock would not be precisely the exact same size as yet another.

To make stocks more quickly and extra uniformly, Thomas Blanchard invented fourteen unique machine tools. Every single machine would be set up for one particular distinct reduce. As the stock was reduce, it would be moved from machine to machine. By mounting the stock to the machine tools with jigs and fixtures, a manufacturer could guarantee that each and every stock would be placed in precisely the exact same position in the machine as the preceding stock. The mounting was in relation to a bearing — a distinct location on the stock that was made use of as a reference point. To verify that the different components of the firearm, and the machine tools themselves, had been constant, a lot of new gauges had been invented. Felicia Johnson Deyrup, Arms Makers of the Connecticut Valley: A Regional Study of the Financial Improvement of the Smaller Arms Sector, 1798-1870, at 97-98 (1948) Thomson at 56–57.

What Blanchard did for stocks, John H. Hall, of the Harpers Ferry Armory, did for
other firearms components. Hall shipped some of his machine tools to Simeon North, in Connecticut. In 1834, Hall and North produced interchangeable firearms. This was the initially time that geographically separate factories had produced interchangeable components. Id. at 58 Merritt Roe Smith, Harpers Ferry Armory and the New Technologies: The Challenge of Adjust 212 (1977).

Mainly because Hall “established the efficacy” of machine tools, he “bolstered the self-assurance amongst arms makers that one particular day they would obtain in a bigger, extra effective manner, what he had carried out on a restricted scale. In this sense, Hall’s perform represented an essential extension of the industrial revolution in America, a mechanical synthesis so unique in degree as to constitute a distinction in type.” Id. at 249.

The technological advances from the federal armories had been broadly shared amongst American makers. The Springfield Armory constructed up a massive network of cooperating private entrepreneurs and insisted that advances in manufacturing methods be broadly shared. By mid-century, what had begun as the mass production of firearms from interchangeable components had turn into globally identified as “the American method of manufacture”—a method that encompassed sewing machines, and, sooner or later typewriters, bicycles, and automobiles. See, e.g., David R. Meyer, Networked Machinists: Higher-Technologies Industries In Antebellum America 81-84, 252-62, 279-80 (2006).

Springfield, in western Massachusetts on the Connecticut River, had been selected for the federal armory in portion simply because of its abundance of waterpower and for the nearby iron ore mines. A lot of private entrepreneurs, which includes Colt and Smith &amp Wesson, produced the exact same decision. The Connecticut River Valley became identified as the Gun Valley. It was the Silicon Valley of its instances, the center of industrial revolution. Id. at 73–103, 229–80.

In brief, the Founding generation was familiar with tremendous advances in firearms technologies. In the American colonial practical experience, the price of fire for an ordinary firearm had quintupled. As of 1791, repeating firearms capable of firing 16 or 22 shots had been demonstrated, but they had been considerably also high-priced for ordinary citizens. The Madison-Monroe administration’s sensible industrial policy, continued below future administrations, led the way towards the mass production of higher excellent firearms at low rates. No one particular in 1791 or 1815 could have foreseen all the firearms innovations in the 19th century. We do know that the American federal government did all it could to make these innovations doable.
