There’s a glitch in CS:GO that allows the R8 Revolver, one of the game’s pistols, to shoot instantly with the Mouse One button while remaining accurate, as one player discovered in a May 25 post to Reddit.
This bug makes the weapon very powerful, as the left click originally has a delay to fire the shot accurately, while the shot with Mouse Two (right click) is instant, but inaccurate. These original mechanics are the reason why almost everyone in the professional scene (and even at the casual level) use the Desert Eagle rather than the R8, as the former allows players to shoot faster while having accuracy. But this glitch could turn CS:GO in the Wild West again, like when the R8 was added in 2015 and it was quite overpowered.
