A handgun is a firearm designed to be operated using only one hand.

This design distinguishes them from long-barreled guns like rifles, shotguns, or machine guns. Long guns are typically held with both hands and braced against the shoulder for stability. Because handguns lack stocks and are much smaller, they are significantly harder to shoot accurately. They also have much shorter effective ranges than their long-barreled counterparts. Today, handguns are most commonly used as sidearms by law enforcement agencies.

The earliest handguns were known as hand cannons.

The oldest known bronze barrel handgun is the Heilongjiang hand cannon from 1288. This weapon was 34 cm long and weighed 3.55 kg. It featured a bulbous base called a Yoshi, which served as the gunpowder chamber. The walls of this chamber were extra thick to withstand explosive pressure. To fire the weapon, a fuse was inserted into a small touch hole to ignite the powder. This explosion propelled the projectile through the barrel.

In 1432, the Joseon dynasty introduced the se-chongtong, the world's first handgun.

This weapon had a total length of 13.8 cm. It utilized a specialized handle called a cheolheumja, which allowed the user to change barrels quickly. The se-chongtong fired a standardized arrow known as chase-jeon. It had a maximum fatal range of approximately 250 meters. Although the Joseon government initially viewed it as a failure due to its short range, it became a popular personal defense weapon. It was used by soldiers, civilians, and even spies known as chetamja.

As technology progressed, new ignition mechanisms were invented to make firing easier. The matchlock appeared in Europe during the mid-15th century.

It used a curved lever called a serpentine to hold a burning slow match. When the lever was pulled, the match dropped into a flash pan to ignite the powder. Around 1500, the wheellock was developed as the first self-igniting firearm.

The wheellock used a spring-loaded steel wheel to spin against pyrite. This action created intense sparks to ignite the gunpowder. This mechanism was much more complex and expensive to manufacture than the matchlock.

By the early 17th century, the flintlock mechanism became a dominant technology.

A flintlock uses a piece of flint to strike a steel surface, creating sparks. These pistols varied greatly in size. Some were less than 15 cm long and could fit in a pocket. Others were over 51 cm long and were carried in holsters on a horse. Some specialized versions, like English duelling pistols, were designed for extreme reliability and accuracy. They were often sold in wooden cases with many accessories.

In the early 19th century, the caplock, or percussion lock, replaced the flintlock.

This change was driven by Reverend Alexander John Forsyth, who patented an ignition system in 1807. He wanted to prevent the puff of smoke from a flintlock from startling birds. The caplock mechanism uses a hammer to strike a small percussion cap. This cap contains mercury fulminate, a chemical made from mercury, nitric acid, and alcohol. When the hammer hits the cap, the chemical explodes. The resulting flames travel through a nipple into the barrel to ignite the main charge. This system was more reliable and resistant to weather than previous designs.

In 1836, Samuel Colt patented the Colt Paterson, the first practical mass-produced revolver.

A revolver uses a rotating cylinder containing multiple chambers. These chambers align with a single, stationary barrel so the user can fire several shots in succession. The original Colt Paterson was a five-shot revolver. Later models, like the Colt Navy Model 1851, improved upon the design. By 1839, manufacturers added reloading levers and capping windows to make the process much faster. This innovation turned the handgun into a highly effective personal weapon.

Modern handguns generally fall into two categories: revolvers and semi-automatic pistols.

Revolvers rely on the rotating cylinder mechanism described earlier. Semi-automatic pistols use different internal processes to fire and reload. These weapons remain central to law enforcement and personal defense. They come in many forms, from tiny pocket pistols to larger service weapons. The evolution from heavy bronze hand cannons to compact modern pistols shows a long history of metallurgical and chemical advancement.
