The Revolver found in DayZ Origins.
The Revolver is an uncommon weapon found in civilian spawns.
The revolver is extremely accurate and has excellent iron sights - It's possible to get headshots on Zombies over 100m. This makes it an effective weapon for looting Helicopter Crash Sites and Barns, Where you can pick off the Zombies without going in harm's way. However, With a low capacity and low fire rate (Around one round a second) the Revolver is virtually useless for PvP.
