It is a single-action revolver with a high capacity 9-shot cylinder. This weapon's high capacity allows for more shots between reloads and allows the player to gain the upper hand, especially in short, intense firefights. In singleplayer, this weapon is capable of killing an enemy with one shot to the chest or head, and is capable of taking down some predatory animals with one shot as well, such as wolves.
Right after reloading, the hammer is left in the uncocked position until the first shot is fired. After this, the hammer becomes cocked and will be cocked back for the remainder of the rounds in the cylinder or until the next reload. This odd occurrence affects all firearms with a visible hammer in single and multiplayer.
