Thank God for all the gun-nuts who supplied the pictures and information about gun types.

Gun Types
Guns can be divided into those that are fired hand-held and those that are braced against the shoulder for firing. The former are called pistols, while the latter are referred to generically as long guns.
Generally soldiers are issued shoulder-fired rifles. Military officers may carry pistols as backup defensive arms.

Pistol
Pistol can refer to the general class of hand-fired guns. A more specific use of the term "pistol" is for self-loading (semiautomatic), magazine-fed hand guns.
Another type of pistol is the revolver. Revolvers have a single barrel but use a rotating cylinder with multiple chambers to provide a repeating action. Because this operating method is fundamentally different from self-loading arms, operation of revolvers is not described further.

Pistol rounds are usually used at distances of less than 50 meters.

Rifle
A rifle is a shoulder-fired arm utilizing a relatively high-velocity round. They are capable of accurate fire out to a few hundred meters.
The term rifle derives from the rifling of the barrel. Rifling is typically helical ridges formed on the inside of the barrel through hammering or drawing. As the projectile engages the rifling it imparts spin. The spin gyroscopically stabilizes the flight of the projectile once it has left the barrel, giving it greater precision over longer distances. Rifled barrels were a major military advance starting before 1800.

Pistol barrels are usually rifled.

Carbine
A carbine is usually a shorter, lighter rifle. It can also refer to pistol-caliber, shoulder-fired light arms. Carbines were originally developed to improve the mobility of horse-riding cavalry soldiers.

Machine Gun
A machine gun is usually a rifle-caliber or larger, crew-served, belt-fed automatic firearm. Traditionally one rifle-caliber machine gun is deployed per platoon-sized (8 person) unit. Larger machine guns, such as the .50 caliber Browning M2 are used in vehicle- or tripod-mounted applications.

Submachine Gun
A submachine gun is a pistol-caliber, magazine-fed, individual automatic firearm. In military environments they are traditionally deployed in special operations commando units where mobility is key, or tank crews where space inside the vehicle is tight. In police environments they are deployed in counter-terrorist or special weapons units.
Since they usually have longer barrels than pistols submachine guns make more efficient use of pistol ammunition and are effective out to about 100 meters, though traditionally they are deployed at shorter distances. They are usually shoulder-fired for better accuracy.

Assault Rifle
A true assault rifle is a small, rifle-sized, fully-automatic arm chambered for an intermediate-power rifle round such as 7.62 x 39mm (Soviet) or 5.56 x 45mm (NATO). Current examples include the AK-47, AK-74, M16, and Steyr AUG. Note that true assault rifles are the fully automatic military versions, not the semi-automatic versions commercially available in the U.S.

The recently designed FN P90 Personal Defense Weapon falls somewhere between the submachine gun and assault rifle categories. It fires a small, light, 5.7 x 28mm rifle-caliber round but is about the size of a submachine gun. The P90 was designed for support troops other than assault infantry, who need full-sized assault rifles. The effectiveness of this new round in combat has not been fully determined.

Shotgun
A shotgun is a shoulder-fired arm. Most have barrels with smooth bores and fire loads of multiple lead or steel shot (balls individually or collectively called shot). Shotguns are found in hunting, target shooting, military, police, and self-defense applications. Shotguns can also fire slugs (a single large projectile) from smooth or rifled barrels. Shot is effective to about 40 meters or less. Slugs are effective out to about 100 meters or less. Shotguns are usually used at the shorter end of these ranges.

less wasted ammo trying to get a head shot but in close quarters i gotta go with the pistol

If it was close range I'd use a shotgun because you don't have to be incredibly accurate and it is possible to hit more than one target with only one pull of the trigger.

Killing them off from a distance is the choice for me.

it's the only one that i know how to use

i want one of everything *.* ..lol but i say..like two Pistols ...They would be easier to carry and more light weight..wont get in the way while kicking some zombie ass in close combat

Need to set up on top of the walmart, take my time to aim and shoot.

*BOOM* Head shot !

Good for close corners

i would shoot their heads first

ZOMBIE SURVIVAL GUIDE SAID SO BITCH

Don't follow that book so blindly. It may have some good ideas, but you need to think up of a more reasonable argument than "the survival guide said so".

I'd just carry a big stash of magazines and shoot into the crowds like wild.

shot gun is alway the best weapon to kill zombies, whit one shoot you may kill 2-3 zombies.

to blow the head of them!

Shotgun is my weapon of choice all the time, all you got to do is blow them away with the shells.

they don't have a chance

machine guns are cool

i pick full auto shotguns(same as a regluer shotgun but if u need a gun that just shots fast in to zombies so u might not have to pump it but it has a 100 drum round, some do)

knee caps then head. pluas u know the amount of pressere to self reloead a shotgun when a zomb-head is 5ft away.

id say this because it has amazing power and small kick along with it shoots as fast your finger moves

And a skorpian sub-machine gun

It kills more Zombies in one shot

one are two shots for every zombie every body should use this if they didn't they would probaly die!!!!

it just depends on what kind of rifle we're talking about

I THING THE FASTEST SHOUTER

Shotguns

if you can't aim I guess a shotgun would do...lol

meelee

it depends on the situation with me i would try to use a silent weapon if its just one zombie
