A Revolver is a type of repeating handgun that uses a rotary cylinder to store ammunition. Compared to magazine-fed pistols, 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 pistols, such as hipfire accuracy, fire rate, and mobility. This makes revolvers more unforgiving than other weapons, but excel in high damage output.
In Modern Warfare 2, the .44 Magnum is not available to the player in the Campaign (excluding Museum), only seen as the signature weapon of General Shepherd. In Modern Warfare 3, the .44 Magnum is only found in the level "Bag and Drag". It is also available in Multiplayer and Surivival Mode. In Ghosts, the .44 Magnum is only used in the last level, but is available in Multiplayer and Extinction Mode. It is also the second to last weapon in Gun Game, where it is equipped with ACOG and Dual Wield. In Safeguard , it is referred to as the Wild Widow.
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 six 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 pistol ammo. This revolver is Raul Menedez's choice of weapon.
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.
Exclusive to the Zombies map "Buried", the Remington New Model Army takes the place of the Python. It is a six shot revolver only obtained through the Mystery Box. With clear sights and moderate recoil the New Model Army performs quite similarly to the Python.
