- "A frame and cylinder conversion that allows the revolver to hold eight rounds of .357 ammunition with an exceptional increase to rate of fire and a near instantaneous trigger action."
- — In-game description
The JAK Gunslinger is a conversion kit for the Basilisk handgun featured in Call of Duty: Modern Warfare III as part of the Aftermarket Parts system. It was added as part of the Season Four update.
The Gunslinger Kit allows the Basilisk to fire instantaneously unlike the other revolvers, which have a small delay before firing to simulate the double-action hammer needing to pull back. As such, it increases fire-rate, trigger response time, recoil control, and magazine size in exchange of damage, gun kick recoil, and range.
