In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger, hammer/firing pin or frizzen, and therefore do not need a sizable receiver behind the barrel to accommodate a moving action, making them far less complex and more robust than revolvers or magazine/belt-fed firearms, but also with much slower rates of fire.
The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. Its invention gave rise to the caplock mechanism or percussion lock system which used percussion caps struck by the hammer to set off the gunpowder charge in rifles and cap and ball firearms. Any firearm using a caplock mechanism is a percussion gun. Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle. Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot.
The lock of a firearm is the mechanism used to initiate firing. It is generally used as a historical term, referring to such mechanisms used in muzzle-loading and early breech-loading firearms, as modern firearms uniformly fire by use of a firing pin to strike the rear of a cartridge. Side-lock refers to the type of construction, in which the individual components of the mechanism are mounted either side of a single plate. The assembly is then mounted to the stock on the side of the firearm. In modern firearm designs, the mechanism to initiate firing is generally constructed within the frame or receiver of the firearm and is referred to as the firing or trigger mechanism.
The Spencer repeating rifle was a 19th-century American lever-action firearm invented by Christopher Spencer. The Spencer carbine was a shorter and lighter version designed for the cavalry.
The Henry repeating rifle is a lever-action tubular magazine rifle. It is famous for having been used at the Battle of the Little Bighorn and having been the basis for the iconic Winchester rifle of the American Wild West.
The Massachusetts Arms Company, of Chicopee Falls, Massachusetts was a manufacturer of firearms and firearm-related products from about 1849 into the early 20th century.
Edward Maynard was an American dentist and firearms inventor, most famous for his breechloading rifle design.
Sharps rifles are a series of large-bore, single-shot, falling-block, breech-loading rifles, beginning with a design by Christian Sharps in 1848 and ceasing production in 1881. They were renowned for long-range accuracy. By 1874, the rifle was available in a variety of calibers, and it was one of the few designs to be successfully adapted to metallic cartridge use. The Sharps rifles became icons of the American Old West with their appearances in many Western-genre films and books. Perhaps as a result, several rifle companies offer reproductions of the Sharps rifle.
The M1819 Hall rifle was a single-shot breech-loading rifle designed by John Hancock Hall, patented on May 21, 1811, and adopted by the U.S. Army in 1819. It was preceded by the Harpers Ferry M1803. It used a pivoting chamber breech design and was made with either flintlock or percussion cap ignition systems. The years of production were from the 1820s to the 1840s at the Harpers Ferry Arsenal. This was the first breech-loading rifle to be adopted in large numbers by any nation's army, but not the first breech-loading military rifle – the Ferguson rifle was used briefly by the British Army in the American Revolutionary War. The Hall rifle remained overshadowed by common muskets and muzzleloading rifles which were still prevalent until the Civil War. The early flintlocks were mostly converted to percussion ignition.
The Colt New Model revolving rifles were early repeating rifles produced by the Colt's Manufacturing Company from 1855 until 1864. The design was essentially similar to revolver type pistols, with a rotating cylinder that held five or six rounds in a variety of calibers from .36 to .64 inches. They were mainly based upon the Colt Model 1855 Sidehammer Pocket Revolver developed by Elisha K. Root. Colt revolving pistols and rifles were attractive mainly because of their high rate of fire. They were used to a limited extent on the Pony Express and made a brief appearance in the American Civil War. However, the rifles were generally disliked by soldiers, and were ultimately discontinued due to serious design flaws.
The .50-70 Government / 12.7 x 45 mm R, also known as the .50-70 Musket, .50-70 Springfield, and .50-1+3⁄4" Sharps) is a black powder cartridge adopted in 1866 for the Springfield Model 1866 trapdoor rifle.
The Burnside carbine was a breech-loading carbine that saw widespread use during the American Civil War.
During the American Civil War, an assortment of small arms found their way onto the battlefield. Though the muzzleloader percussion cap rifled musket was the most numerous weapon, being standard issue for the Union and Confederate armies, many other firearms, ranging from the single-shot breech-loading Sharps and Burnside rifles to the Spencer and the Henry rifles - two of the world's first repeating rifles - were issued by the hundreds of thousands, mostly by the Union. The Civil War brought many advances in firearms technology, most notably the widespread use of rifled barrels.
The Merrill carbine was a breechloader firearm designed by Baltimore, Maryland gunsmith and inventor James H. Merrill. It was one of several firearms either manufactured or altered by Merrill in fulfillment of contracts with the Union government during the U.S. Civil War.
The Smith Carbine was a .50 caliber breech-loading black powder percussion rifle patented by Gilbert Smith on June 23, 1857 and successfully completed the military trials of the late 1850s. It was used by various cavalry units during the American Civil War.
The Gallager carbine is an American black powder breechloading percussion rifle produced in the American Civil War.
The Starr carbine was a breechloading single-shot rifle used by the United States Army. Designed in 1858, the Starr was primarily used by cavalry soldiers in the American Civil War.
The term Joslyn Rifle refers to a series of rifles produced in the mid-19th century. The term is often used to refer specifically to the Joslyn Model 1861/1862, which was the first mass-produced breech-loading rifle produced at the Springfield Armory.
The Springfield Model 1855 was a rifled musket widely used in the American Civil War. It exploited the advantages of the new conical Minié ball, which could be deadly at over 1,000 yards (910 m). It was a standard infantry weapon for Union and Confederates alike, until the Springfield Model 1861 supplanted it, obviating the use of the insufficiently weather resistant Maynard tape primer.
Frank Wesson rifles were a series of single-shot rifles manufactured between 1859 and 1888 in Worcester, Massachusetts. They were purchased by many state governments during the American Civil War, including Illinois, Indiana, Kansas, Kentucky, Missouri, and Ohio. They were one of the first rifles to use rimfire metallic cartridges.
