 History of Gun .
 In 1836, an American, Samuel Colt patented the
first revolver mechanism that led to the
widespread use of the revolver.
 Most amazing, yet brutal discovery of 19th
Century.
 A revolver is a repeating firearm that has a
revolving cylinder containing
multiple chambers and at least one barrel for
firing. The term "revolver" refers to
ahandgun, but other weapons may also have
a revolving chamber. These include some
models of grenade launchers, shotguns,
and rifles.
Revolvers usually hold six shots. The ATF defines 
a pistol as any handgun that does not contain its 
ammunition in a revolving cylinder. Most pistols 
have a removable magazine into which bullets are 
loaded. The magazine is then inserted into the 
hollow handgrip of the gun.
How Guns Function ?
 Apply explosive pressure
behind a projectile to launch
it down a barrel.
 Complete mechanically
operated machine
 A combination of a
projectile (the bullet), a
propellant (gunpowder, for
example) and a primer (the
explosive cap), all contained
in one metal package.

Lets move in
depth
How Guns Function ?
 Initially, the trigger lever
pushes the hammer
backward.
 As it moves backward, the
hammer compresses a
metal spring in the gun
stock (the handle).
 At the same time, the
trigger rotates the cylinder
so the next breech
chamber is positioned in
front of the gun barrel.
 When you pull the trigger all the way
back, the lever releases the hammer.
 The compressed spring drives the
hammer forward.
 The hammer slams into the primer at
the back of the cartridge, igniting the
primer.
 The primer sets off the propellent.
 The exploding propellent drives the
bullet out of the gun at high speed.
 Gatling Gun- Most older
and popular design.
 Fully automatic machine gun use the power of the
cartridge explosion to reload and re-cock the gun
after each shot.
 There are three basic mechanisms for harnessing this
power:
1)Recoil systems
2)Blowback systems
3)Gas mechanisms
 A locking mechanism
holds together the barrel
and the breach bolt.
 Bolt and the barrel can
move freely in the gun
housing
 When the trigger is pulled,
the sear releases the bolt,
and the spring drives it
forward.
 After the bolt chambers
the cartridge, the firing pin
sets off the primer, which
ignites the propellant
 The Zig zag revolver is a 3D printed .38 Revolver
made public in May 2014. It was created using
an $500 plastic 3D-printer used, the name of the
printer was not revealed by the creator.[41]
It was
created by a Japanese citizen
from Kawasaki named Yoshitomo Imura He was
arrested in May 2014 after he had posted a video
online of himself firing a 3D printed Zig Zag
revolver.It is the first 3D printed Japanese gun in
the world which can discharge live cartridges.[
 The explosive gas from
the cartridge drives the
bullet down the barrel. At
the same time, the gas
pressure pushes in the
opposite direction, forcing
the bolt backward.
 Similar to Blowback
system.
 The main addition is a
narrow piston, attached
to the bolt, that slides
back and forth in a
cylinder positioned
above the gun barrel
How Guns Function ?
 In order to protect from criminals and wild
animals and other aspects which may be
harmful to us .
 Especially these are legal in military services
where we protect our country from foreign
invaders.

How Guns Function ?
 Machine gun had been one of the most important
military developments in the history of man. It
has been the reason behind the fall of many
nations, repressing revolutions, overthrowing
governments and ending wars.
 Gun manufacturers are continually adding new
modifications to machine guns, but the basic
mechanism has remained the same for more than
a hundred years. Some of the modern machine
guns can be fired using a remote control.
