Single-shot firearms are firearms that hold only a single round of ammunition, and must be reloaded after each shot. The history of firearms began with single-shot designs, and many centuries passed before multi-shot designs became commonplace. Single-shot designs are less complex than revolvers or magazine-fed firearms, and many single-shot designs are still produced by many manufacturers, in both cartridge- and non-cartridge varieties, from zip guns to the highest-quality shooting-match weapons.

Most firearms before the era of cartridges were single-shot and muzzleloading, with the exception of the cap-and-ball revolvers, such as Samuel Colt's, which appeared shortly before the cartridge era.
Many of the early cartridge-fed rifles were single-shot designs, taking advantage of the strength and simplicity of single-shot actions. A good example is the "trapdoor" or Allin action used in early cartridge conversions of 1863 Springfield muzzleloading rifles. The conversion consisted of filing out (or later milling out) the rear of the barrel, and attaching a folding bolt, the "trapdoor", that flipped up and forwards to allow the cartridge to be loaded in the breech. Once loaded, the bolt was closed and latched in place, holding the round securely in place. The bolt contained a firing pin that used the existing percussion hammer, so no changes were required to the lock. After firing, the act of opening the bolt would partially extract the fired case from the chamber, allowing it to be removed. In 1866, the United States standardized on the .50-70 cartridge, chambered in trapdoor conversions of rifled muskets used in the American Civil War. The trapdoor mechanism continued with the adoption of the Springfield 1873 rifle, chambered in the new .45-70 cartridge. The Springfield stayed in service until 1893, when it was replaced by the Krag-Jørgensen bolt-action rifle.
Another muzzleloader conversion similar in concept to the Allin action was the British Snider-Enfield, also introduced in 1866, which hinged to the side rather than forward. Unlike the US Army, which kept its trapdoors for decades, the British soon moved beyond the Snider to a more sophisticated dropping-block single-shot action somewhat resembling the Peabody action. Martini-Henrys were the standard British rifles of the late Victorian era, and Martini-Enfield conversions continued in second-line service until the Second World War.
Single-shot rifles were the preferred tools of big-game hunters in the later 19th century. The buffalo hunters of the American West used Sharps, Remington and Springfield single-shots; ivory and trophy hunters in Africa and Asia used Martini and break-action "express rifles" and "elephant guns." These rifles were designed for very large black-powder cartridges, from military-issue .45-70 on up to the enormous .50-140 Sharps and .500 Express; early repeating actions were not capable of handling rounds of this power and physical size. The single-shot big-game rifle would only be displaced by bolt action repeaters firing high-velocity smokeless-powder cartridges in the early 20th century.
After the advent of high-powered repeating rifles, single-shot rifles were primarily used for target shooting matches, with the first official match shooting event, opening at Creedmoor, Long Island in 1872. From about 1872 until the U.S. entry into World War I (1917), target shooting with single-shot rifles was nearly as popular in America as golf is today. During that golden age of match shooting, the most popular target rifles were made by Bullard, Stevens, Remington, Maynard, Ballard, Farrow, and Winchester. Calibers used by some of these rifles during matches ranged from the .25/20, .32/40, .33, .35, .35-55, .38-55, .40-50, .40/70, and a host of .44's (.44/105, .44/77, etc.) for over-600-yard shooting at Creedmoor. But two calibers maintained consistency throughout their tenure during the single-shot era: the .32-40 and the .38-55 calibers. The minimum standard in the beginning of the sport had been 200 yard firing from the standing position (off-hand position). No rifle scopes, no bench rests, no prone (lying down on the front) positions, but shooting, as famed rifle barrel maker, Harry Melville Pope (1861–1950), once stated, "standing on his hind legs and shooting like a man."  The .32-40 and .38-55 were able to buck the wind better at 200 yards, and not wear the rifleman out by heavy recoil, all while sustaining great accuracy. In the end though, it was the .32-40 single shot rifle that became the dean of match shooters, as the recoil from the .38-55 took its toll after hundreds of rounds had been fired during a match.
In 1878, John Moses Browning patented arguably the greatest single-shot rifle ever produced: after Browning sold his design to Winchester it was brought out as the Model 1885 Winchester Single Shot Rifle. Although fewer than 200,000 Model 1885 Single Shots were built, it remained in production from 1885 to 1920.
Remington, Sharps, and Browning all made single-shot rifles using different actions, such as the rolling block and falling block. These rifles were originally chambered in large black powder cartridges, such as .50-110, and were used for hunting large game, often bison. Later production rifles would be in popular smokeless powder cartridges, such as the .30-40 Krag.
Single-shot rifles co-existed for some time with the lever action rifle, but they began to fade out of manufacture with the advent of reliable bolt action rifles.
Single-shot pistols were less common, as the revolver was a fairly mature technology by the advent of cartridge arms, and cartridge conversions existed for the common models of revolver. Versions did exist, which usually fell into two categories: single shot derringers, and target pistols, which were essentially single-shot rifle actions cut down to pistol size. The Remington Rolling Block is perhaps the most well known of these. As the era of single-shot rifles faded, so did these early single-shot pistols.
In 1907, J. Stevens Arms, a maker of inexpensive break-open single-shot rifles in pistol calibers, started making pistol versions of their rifles. This pistol was chambered in .22 Long Rifle and came with adjustable iron sights and grips designed for target shooting. These models were discontinued in 1939.
Single-barrel shotguns have always been popular as an inexpensive alternative to double-barreled shotguns. Single shotguns are almost always break-open designs, like the double-barreled designs, but far less expensive since they do not require the precise aligning of parallel barrels. Single shotguns are also lightest, which can be an advantage if they are carried hunting, though it does mean they have the most felt recoil. Single shotguns are not widely used in shotgun sports, as most events require the ability to quickly fire two successive shots, which would require reloading a single-shot design while a target is in the air. These simple shotguns are often referred to as a "kitchen door gun" or a "farm gun" due to its low cost as a self-defense weapon.
Types of single-shot cartridge actions
The earliest metallic-cartridge breechloaders designed for general military issue began as conversions of muzzle-loading rifle-muskets. The upper rear portion of the barrel was filed or milled away and replaced by a hinged breechblock which opened upward to permit loading. An internal angled firing pin allowed the re-use of the rifle's existing side-hammer. The Allin action made by Springfield Arsenal in the US hinged forward; the Snider-Enfield used by the British opened to the side. Whereas the British quickly replaced the Snider with a dropping-block Peabody style Martini action, the US Army felt the trapdoor action to be adequate and followed its muzzleloader conversions with the new-production Springfield Model 1873, which was the principal longarm of the Indian Wars and was still in service with some units in the Spanish-American War.
Other trapdoor actions include the rare Confederate Tarpley carbine, the Austrian Wanzl, the Belgian Albini-Braendlin rifle and Terssen conversion (some of which were made from French 1777 pattern flintlocks!), the M1842/59/67 Swiss Milbank-Amsler, the M1859/67 Spanish Berdan, and the Colt-manufactured Russian Berdan Type I. All of these designs save the 1863 Tarpley date from the period 1865-1869, and all but the Tarpley and the Russian Berdan were conversions from muzzle-loaders.
Perhaps the most common type of single-shot action, usually found in shotguns, small pistols, and black-powder "elephant" guns, a break action connects the barrel assembly to the breechblock with a hinge. When a locking latch is released, the barrel assembly pivots away from the receiver, opening the breech and, at least on better firearms, partially extracting the spent cartridge.
Rolling block actions
In a rolling block action the breechblock takes the form of a part-cylinder, with a pivot pin through its axis. The operator rotates or "rolls" the block to open and close the breech; it is a simple, rugged and reliable design. Rolling blocks are most often associated with firearms made by Remington in the later 19th century; in the Remington action the hammer serves to lock the breech closed at the moment of firing, and the block in turn prevents the hammer from falling with the breech open. An interesting variation of the rolling block was the Austrian M1867 Werndl-Holub, in which the pivot pin was parallel to the barrel and the block rotated sideways.
Dropping block actions
These are actions wherein the breechblock lowers or "drops" into the receiver to open the breech, usually actuated by an underlever. There are two principal types of dropping block: the tilting block and the falling block.
Tilting block actions
In a tilting or pivoting block action, the breechblock is hinged at the rear. When the lever is operated, the block tilts down and forward, exposing the chamber. The best-known pivoting block designs are the Peabody, the Peabody-Martini, and Ballard actions.
The original Peabody rifles, manufactured by the Providence Tool Company, used a manually cocked side-hammer. Swiss gunsmith Friedrich Martini devised an action that resembled the Peabody but incorporated a hammerless striker cocked by the operating lever with the same motion that pivoted the block. The 1871 Martini-Henry which replaced the "trapdoor" Snider-Enfield was the standard British Army rifle of the later Victorian era, and the Martini was also a popular action for civilian rifles.
Charles H. Ballard's self-cocking tilting-block action was produced by the Marlin Firearms Company from 1875, and earned a superlative reputation among long-range "Creedmoor" target shooters. Surviving Marlin Ballards are today highly prized by collectors, especially those mounted in the elaborate Swiss-style Schützen stocks of the day.
Falling block actions
In a falling block action the block does not pivot, but rather slides vertically in a slot milled into the receiver. Falling blocks are among the strongest smallarm actions ever produced, and are also used in heavy artillery. Well-known falling block designs include the Sharps rifles and carbines, the Browning/Winchester Single Shot, the Farquharson rifle, and the modern Ruger No. 1.
Although bolt actions are usually associated with fixed or detachable box magazines, in fact the first general-issue military breechloader was a single-shot bolt action: the paper-cartridge Prussian Needle Gun of 1841. France countered in 1866 with its superior Chassepot rifle, also a paper-cartridge bolt action. The first metallic-cartridge bolt actions in general military service were the Berdan Type II introduced by Russia in 1870, the Mauser Model 1871, and a modified Chassepot, the Gras rifle of 1874; all these were single-shots.
Today most top-level smallbore match rifles are single-shot bolt actions.
Single-shot bolt actions in .22 caliber were also widely manufactured as inexpensive "boys' guns" in the earlier 20th century; and there have been a few single-shot bolt-action shotguns, usually in .410 bore.
Other single shot actions
- The Ferguson rifle : British Major Patrick Ferguson designed his rifle, considered to be the first military breechloader, in the 1770s. A plug-shaped breechblock was screw-threaded so that rotating the handle underneath would lower and raise it for loading with ball and loose powder; the flintlock action still required conventional priming.
- The Hall rifle : The United States' first breechloading cavalry carbine, the Hall was introduced in 1819. The lever tipped the breechblock including the chamber upwards and back, allowing it to be loaded with powder and ball without the inconvenience of loading and ramming from the muzzle. Originally flintlocks, Halls later were made as or converted to percussion locks.
- The Kammerlader : A crank-operated Norwegian firearm produced around the time of the Prussian Needle-gun. Originally used a paper cartridge. Later many were converted to rimfire.
- The Burnside carbine : Invented by future general Ambrose Burnside in 1857, this percussion-cap carbine became the third-most common cavalry breechloader in the Civil War after the Sharps and Spencer. Essentially a modification of the Hall concept, the Burnside featured a unique conical cartridge with a crushable hollow front rim, designed to seal the breech on closing.
- The Rising breech carbine : An unusual action produced by Bilharz, Hall and Co. for the southern Confederacy, the rising breech's underlever caused the breechblock including the chamber to slide vertically above the line of the barrel, the reverse of a falling-block; the chamber was loaded from the front with a paper cartridge.
- The Morse Carbine : Its action is similar to the Hall rifle but the shape of its chamber is different.
- Winchester Model 55 : An unconventional hybrid of a single-shot and a semi-automatic, this .22-caliber rifle ejected the fired case and recocked itself like a conventional blowback-operated self-loader, but it lacked a magazine and had to be manually reloaded for each shot.
Although non-cartridge single-shot firearms are still made in hobbyist contexts (for example, replicas of antique guns), this discussion focuses on newer designs employing cartridges.
The modern era of single-shot firearms is most visible in the realm of pistols. Remington introduced the single-shot bolt-action XP-100 pistol in 1963, which heralded the era of high-performance, high-velocity pistols. The .221 Fireball cartridge lived up to its name by reaching velocities of 2700 ft/s (823 m/s) from a 10.5" (26.7 cm) barrel. Essentially a shortened .222 Remington, the compact .221 Fireball delivered accuracy exceeding many rifles, out to ranges unheard of for other handguns.
Even bigger than the XP-100, the 1967 introduction of the Thompson Center Arms Contender pistol changed handgun sports forever. The Contender was a break-open design that allowed barrels to be changed by the shooter in minutes. Available in calibers from .22 Long Rifle up to .45-70, and in barrel lengths of 8, 10, and 14 inches (20, 25, and 35.5 cm), the Contender could, in the right hands, handle any type of game, and delivered rifle-like accuracy to match the XP-100.
Many other manufacturers make single-shot pistols, most based on the bolt action rifle, with barrels generally ranging from 10 to 15 inches (25 to 38 cm). Single-shots dominate handgun metallic silhouette shooting, and single-shots are the most common handguns used for hunting.
Single-shot pistols have sometimes found popularity among insurgents, resistance fighters, and street gangs. The mass-produced, low-cost Liberator pistol of World War II, which was manufactured and distributed by U.S. forces to Allied Resistance forces and Guerrilla fighters as an assassination pistol, is the most common example of a mass-produced single-shot pistol. More than a million units were produced and distributed freely and many remain in private hands. A few varieties of zip guns could also be considered single shot pistols. In recent years these improvised firearms have become more common in the hands of criminals and insurgents, especially when manufactured firearms are difficult to acquire.
In 1966, Sturm, Ruger introduced their first true rifle. Their earlier long guns had been carbines, the first a .44 Magnum and the next the highly popular Ruger 10/22 in .22 Long Rifle. The rifle Ruger brought out, named simply "#1", (Ruger No. 1) uses a falling block action, and is available in a wide selection of calibers from .22 Hornet to .458 Winchester Magnum. The #1 has always been sought after by shooters who appreciate the compact size of a single shot rifle, and the falling block action cuts about four inches off the length of the rifle for a given barrel length. From 1972 to 1987, Ruger also made a less expensive version of the #1, the #3. The #3, which sold for about half the price of a #1, used a simplified, non-locking lever for the falling block action, and came with an uncheckered stock.
In 1985 Browning re-introduced the famous Winchester Model 1885 single shot rifles in popular calibers, but under the Browning name. Although the Winchester Single Shot gained fame under the Winchester brand name, it was John Moses Browning that designed the rifle, selling the rights to Winchester in the early 1880s. The Browning Single Shot Rifle was in production from 1985 to 2001.
The majority of rifles made by Cooper are single-shot bolt-action rifles. Many of their rifles are specially crafted to suit long-range varmint hunting, where the accuracy of the single-shot action is helpful.
Remington has once again made their No. 1 Rolling Block rifles available  through their custom shop.
New England Firearms (H&R)
One of the most common single-action rifles would be the New England Firearms inexpensive break-open rifles, which are built on their 12 gauge break-open shotgun actions. The rifles however are made on a heat treated steel action, and the shotgun actions are not heat treated. Any rifle frame may accept rifle or shotgun barrels, the shotgun frames however are only safe for shotgun barrels. These were originally built by Harrington & Richardson starting in 1871. H&R was later acquired by NEF, and both are now part of the Marlin Firearms family. Rifles are sold both under the NEF and the H&R names. These rifles are quite accurate, and often less than half the price of a bolt action rifle in the same caliber.
In 2005, Winchester re-marketed their legendary Model 1885 Single Shot Rifle, under their Limited Series category. The modern calibers of .17 was offered in a Low Wall design, and the .243 and .30-06 were of the High Wall type. The most faithful of the reproductions are the Traditional Hunter Limited Series model 1885 Single Shots, as they have the original style steel crescent butt plates, and folding steel tang rear sights, with full length octagon barrels. The Traditional Hunters are chambered in the 19th century calibers of .45-90 BPCR, .45-70, .405, and .38-55. Test firing of some of these Winchesters showed that they are high quality in construction, using the latest technology and modern steel, they are stronger and safer than their 19th century predecessors; and accuracy from their factory (non-custom) barrels were exceptionally good; especially at 200 yards. However, their price will be reflected in that quality. The popularity of Cowboy action shooting has also had an impact on the availability of single-shot rifles, with many replicas of the old black powder rifles, particularly the Sharps, now being available.
Sharps rifles were a staple of the buffalo hunters in the late 19th century. Recently they have had a resurgence in popularity for hunting large game as well as historical firearms events and black powder cartridge (BPCR) competitions. Much of the current popularity is due to the film Quigley Down Under that featured a Sharps Model 1874 rifle.
