The Basic Parts of a Firearm
Whether you’re a beginner or seasoned shooter, knowing the basics of a firearm is essential. Read on to learn the main parts of a firearm, including their names and what they do.
Barrel
The barrel is a vital part of any firearm. It is the point of contact between the projectile and the propellant gases that are forced into the bore by the hammer.
The rifling in the barrel grips the bullet as it travels down the bore, making it more stable in flight. It also increases the amount of pressure on the propellant gas to increase the projectile’s speed and range.
In addition, the barrel can be shaped to reduce weight and improve cooling. For example, some firearms use composite barrels that are shaved down and an exterior sleeve slipped over them to improve rigidity and weight.
Frame
The frame is a basic structure that supports the rest of the firearm. This is a crucial feature for safety, since it prevents objects from entering the chamber.
The frame also protects the cylinder from impact and sudden loads. This includes the force of braking and acceleration.
Moreover, it handles the lateral forces transmitted by the road. It also deals with the torsional and vertical twisting caused by the traction of the vehicle.
The frame also serves as a support for the weight of the passengers and cargo load of the vehicle. It also handles the torsional and vertical stresses that are transmitted by the movement of the vehicle during braking and acceleration.
Magazine
The magazine is the area of a gun that holds ammunition and feeds it into the firearm’s firing chamber. This is a standard feature on all guns, including pistols and rifles.
There are many types of magazines. The most common is a box magazine. These magazines are shaped like boxes and have a spring that pushes the rounds into the gun’s chamber.
Some guns, such as semi-automatic pistols and some rifles, have detachable magazines. These are reloaded by hand or with a clip.
It’s important to understand the differences between magazines and clips. This will help you avoid misunderstandings and awkward situations. Knowing the difference will also help you make better decisions when you visit a gun store. It may even save you a lot of time and money!
Trigger
The trigger of a firearm is the small lever that you pull to fire it. It is used to fire a shotgun, a pistol, or a rifle. The trigger disengages the sear on the weapon and sets off a series of reactions that ultimately result in the firing pin striking a cartridge primer and detonating the powder in the bullet.
There are a few different types of triggers. The most common type is a single-action trigger, which performs one task and releases the hammer/firing pin. This is typically found on pistols and revolvers, though it can be seen on a few other types of firearms as well.
Safety
Safety features are the mechanical devices that block or disengage the firearm’s action to prevent accidental discharge. These are designed to protect the shooter but should never be relied on to eliminate all risk of injury or fire.
Safeties are often referred to as “active” or “passive.” Active safeties are designed to be activated by the shooter and deactivated by the shooter. Passive safeties, on the other hand, are not designed to be activated or deactivated by the shooter; they work automatically when the gun is unloaded and closed.
Some active safeties work by preventing the firing pin from contacting the primer until the user disengages the safety. These are referred to as trigger-blocking safeties, and they are found on many break-action over/under shotguns.
