What gun fighter in the old west got the most kills?

While it's difficult to determine the exact number of kills attributed to any gunfighter in the Old West due to the lack of reliable records, many historians suggest that John Wesley Hardin was one of the deadliest. Hardin claimed to have killed around 27 men, though the actual number is disputed and could be lower. His reputation for violence and quick draw made him infamous, but the chaotic nature of the time means that precise figures are elusive.
