Gun

Guns are long-ranged weapons that use an explosive charge (in a similar manner to the black powder charges used by real-world flintlock weaponry) to propel a bullet. They are similar to bows and crossbows in use; all three use the shooting skill and related hunter skills. Character stats are applied the same way for each type, although the item stats will be different for each type.

Ancient times
Titanstrike was Azeroth's first firearm.

Third War
Using the legendary single-shot Blunderbuss Long Rifles, the brave dwarven riflemen served during the War.

Guns could also be found in the hand of humans. Pierce's Pistols was a shop in Stratholme before the war started, and the Gilneans were known for using pistols as well.

Acquiring and upgrading
There are several ways to acquire a gun. Like all other weapons and armor, they can be:
 * Bought from various types of vendors
 * Looted from mobs
 * Rewarded from quests
 * Crafted by engineers

There are also different ways to improve your gun:
 * Simply acquire a better gun with better stats
 * Add an engineer-crafted scope on it

History
Different things related to guns have changed since World of Warcraft began:

Training
Before Patch 4.0.1, only Dwarf and Tauren hunters started with the gun skill. All other hunters, rogues and warriors had to learn the gun skill from trainers (see weapon trainers for details).

Dwarves have a racial trait that improves their ability to use guns - Gun Specialization: Increase Gun Critical Hit chance by 1%

Ammo
Prior to patch 4.0.1, players also required bullets (an item type) to fire their guns. The patch removed the need for ammunition, which also removed arrows from bows and crossbows. Now, guns will endlessly fire and only stop firing when they break.

Ammo Pouches
An Ammo Pouch was previously a type of bag-item which held only bullets. Bullets could be stored both in ammo pouches or in regular bags, but the pouches usually had more inventory slots than regular bags. With the removal of ammunition in patch 4.0.1, ammo pouches were also removed from the game (they were no longer craftable, and any existing ones were converted into normal bags).

In the RPG
Firearms are a relatively new dwarven invention. Despite the dangers of dealing with volatile explosives, dwarves are fascinated by the possibilities. Dwarven gunmakers constantly tinker with the guns they craft, trying out new designs and upgrades, naming and decorating their weapons.

Gun Types
This basic firearm deals damage to anyone in a 5-foot wide path beyond that distance, out to maximum range. It holds a single shot and thereafter it is required to reload for another shot.

A flintlock pistol is powerful but inaccurate, not so much a small version of the long rifle as it is like firing a bomb though a short tube. It holds a single shot and thereafter it is required to reload for another shot.
 * Flintlock Pistol

The king of small arms, a long rifle is nearly as long as a dwarf is tall. Thanks to the innovative barrel design, a skilled sharpshooter can use the long rifle to knock an apple of an orc’s head from nearly half a mile away – assuming the rifleman can resist the urge to shoot the orc instead. The long rifle holds a single shot and thereafter it is required to reload for another shot.

Outlaw rogue Pistol Shot
Outlaw rogues have a ability Pistol Shot where they draw a concealed pistol and fire a quick shot at an enemy.
