A long gun is a specific category of firearms defined by its long barrel. In the study of small arms, these are often called longarms. They are designed to be held with both hands. The user also braces the firearm against their shoulder during use. This design distinguishes them from handguns. A handgun can be fired while being held in only one hand.

The mechanics of a long gun provide several functional advantages. Most long guns feature a front grip, also known as a forearm, and a shoulder stock. These components allow a user to hold the firearm much more steadily than a handgun. The length of the barrel also creates a greater distance between the front and rear sights. This increased distance provides more precision when a user is aiming. Furthermore, the presence of a stock makes it easier to use advanced aiming tools. These include red dot sights or telescopic sights.

Long guns also manage the physics of firing more effectively. When a firearm is discharged, it produces recoil. Recoil is the backward push felt by the user. Because a long gun has a stock braced against the shoulder, this recoil is transferred directly into the user's body. This is different from a handgun, where all recoil must be transferred to the arms. This mechanism allows for better control of aim. It also enables the use of larger amounts of propellant, such as gunpowder. Because long guns have more mass, they can fire larger projectiles at higher velocities. This results in better penetration and accuracy over long distances.

There are many different types of small arms classified as long guns. These include shotguns, which are designed to fire many small projectiles at once. Other types include carbines, submachine guns, and assault rifles. There are also specialized tools like sniper rifles and designated marksman rifles. Some are built for heavy use, such as light, medium, or heavy machine guns. Other categories include personal defense weapons and anti-material rifles. While shotguns are effective at close ranges, they have diminished usefulness at long distances. Even when using shotgun slugs, they are mostly effective up to about 50 yards.

Laws in different countries regulate the minimum length of these barrels. In the United States, the National Firearms Act sets specific requirements. Rifle barrels must be at least 16 inches long. Shotgun barrels must be at least 18 inches long. For long guns with detachable or folding stocks, the U.S. requires a minimum length of 26 inches with the stock extended. Canada also has strict rules for these firearms. Canada sets a minimum length of 457 mm for both rifles and shotguns. They also establish a minimum fireable length for guns with folding or detachable stocks.

Despite their advantages, long guns have certain disadvantages. They generally have a greater mass than handguns. This makes them more expensive to manufacture and more costly to transport. The weight also makes them more difficult and tiring to carry. The increased moment of inertia makes them slower to traverse or elevate. This means it can be more difficult to adjust the aim quickly. Additionally, their large size makes them hard to conceal. They can be inconvenient to use in confined quarters and require more storage space.

Historically, the term "long gun" was also used in naval contexts. On sailing vessels, a long gun was the standard type of cannon. This name helped distinguish them from carronades, which were much shorter. In informal naval usage, people combined the length with the weight of the shot. They used terms like "long 9s" to describe these weapons. This referred to full-length cannons that fired a 9-pound round shot.

Understanding long guns requires looking at how they relate to broader systems of physics and law. They demonstrate how mass and stability affect human movement and aim. They also show how legal frameworks, like the National Firearms Act, manage technology. From the heavy cannons on old ships to modern machine guns, the long gun remains a significant tool in history. Its design focuses on the balance between power, precision, and the physical limits of the user.
