The R8 Revolver is the third pistol to be introduced to Global Offensive since the game's retail release. It can be switched out for the Desert Eagle in-game. The Revolver is capable of firing 8 rounds via two separate attacks with only 8 rounds in reserve. The primary attack draws the hammer back before firing. As the hammer is drawn back, the accuracy of the revolver increases, movement speed drops to 180 units per second and then the gun fires after a 0.2 second delay. The secondary attack is a quick shot using the fanning technique, resulting in a much faster but less accurate shot.

In comparison to the Desert Eagle, this weapon deals more damage and is capable in killing a player at close range in two hits against an armored opponent. The primary fire is more accurate and can fire one shot more before reloading. On the downside, primary fire is much slower, requires to lower the hammer before able to fire a shot, the movement speed is lowered to 180.
