A Revolver is a type of repeating firearm that uses a rotary cylinder to store ammunition. Compared to handguns, Revolvers generally have higher power, but at the expense of lower magazine size and higher recoil. Many statistics generally remain the same between revolvers and handguns, such as hipfire accuracy, fire rate, and mobility. This makes Revolvers more unforgiving than other weapons, but excel in high damage output.
The .357 Magnum is unique to the Call of Duty: World at War multiplayer and is never seen during the campaign. It deals the most damage out of all handguns available in multiplayer and usually kills in two shots to the chest. It is also found in Zombies, and is a one-hit kill until Round 7-10.
The Python appears in Call of Duty: Black Ops. It appears in the missions Executive Order, S.O.G. and Victor Charlie. The Python also appears in multiplayer and is unlocked at level 18. It deals the most damage of all Handguns, but has high visual recoil, only has 6 shots in the cylinder, and has a slow reload. In Zombies, it can only be obtained out of the Mystery Box. It is powerful, but has a slow reload and low capacity. It is a one-hit kill until Round 9.
The Python returns in Call of Duty: Black Ops II, but only in Zombies. It performs very similarly to the version that appears in Black Ops, the only main difference being the firing sound.
The Executioner (formerly known as the Raging Judge) is a revolver that appears in Call of Duty: Black Ops II. However, unlike any other weapon in the series, the Executioner fires 28-gauge shotgun shells rather than conventional ammunition.
The Executioner appears in Zombies out of the Mystery Box on all available maps. This gun has a slow reload and small mag capacity, but has very high damage.
