Weapons in Redemption

Weapons come in a large variety in Red Dead Redemption. They are essential to survival and are an integral part of everyday life in the American west. The player will be able to use a range of weapons including outdated manually-operated weapons and cutting edge fully automatics.

To an extent, weapons and ammunition are represented on the character model.

In Multiplayer game modes it is also possible by completing a set of weapon challenges to unlock a golden version of various firearms.

Inventory
The player can carry all weapons that they pick up. Each weapon occupies a slot on the weapon inventory wheel. The player can switch between guns of the same slot. Only one pistol and one long-gun appear on the character model. When dueling, Marston will make use of whichever pistol or revolver is currently equipped. There is a slot for each of the following:
 * Pistols
 * Shotguns
 * Rifles
 * Scoped Rifles
 * Thrown Weapons
 * Fists
 * The Hunting Knife
 * The Lasso

Marston can also buy a Bandolier to hold twice as much ammunition for repeaters and rifles, as well as adding it to Marston's appearance.

Ammunition
Ammunition for the weapons of Red Dead Redemption are split into the distinct firearm categories, and are all interchangeable within these categories. It should be noted that in reality, very few of any two given firearms would be able to interchangeably use ammunition in the time that Red Dead Redemption takes place. Although, in this day and age, most munitions have been standardized.
 * Revolver Ammo
 * Pistol Ammo
 * Repeater Ammo
 * Rifle Ammo
 * Shotgun Ammo
 * Sniper Rifle Ammo

Thrown Weapons
In addition to firearms, the player can obtain various thrown weapons:

Weapon Challenges
Completing weapon challenges in multiplayer, such as getting a certain amount of headshots with a gun, will award you the golden version of the firearm. It is currently unknown what else the weapon challenges can unlock.
