How a Gun Works?

Dear Spy,

Today’s lesson shall focus on another important spy equipment. Do not leave home without it. Yes, it’s your gun!

As a professional spy you should carry along your gun when on duty. But, did you know exactly how a gun works?

There are many different guns available on market such as Flintlock Guns, Revolvers, Machine Guns, Nail Guns, Rocket-Propelled Grenades and many more.

A basic gun has the following parts:

chamber + breech lock, barrel, striker (firing pin) and trigger.

A cartridge (eg.,a shotshell) has a case, primer (the explosive cap), propellant (gunpowder), wadding (in a shotshell), and load (pellets or slug in a shotshell.)

The cartridge is loaded into chamber and held in place (sealed) with the breech lock. To fire, this sequence of events happens:

* trigger releases a hammer (click on the trigger to fire the gun).

* hammer strikes the firing pin

* firing pin strikes the primer, igniting it (the primer explodes).

* ignited primer ignites the propellant.

* propellant burns rapidly, building pressure behind the wadding.

* wadding and load are propelled down the barrel by expanding gases.

Rifles and pistols work the same way, except a solid bullet is used which makes its own seal against the barrel (no wadding). These also have "rifling" - twisted grooves in the barrel to make the bullet spin. This makes them more accurate than a shotgun or a smoothbore rifle.

A longer barrel improves stability, since it spins the bullet for longer. Extending the barrel also increases the speed of the bullet, since the gas pressure accelerates the bullet for a longer period of time.

With a simple and short explanation above, hope everyone already understood the basic concept of how a gun works.Please take a good care of your spy equipment and enjoy become a spy!
