Python

The Revolver is a weapon featured in Grand Theft Auto: Vice City, Grand Theft Auto: Liberty City Stories, Grand Theft Auto: Vice City Stories and Grand Theft Auto: Chinatown Wars. It was also originally going to be featured in Grand Theft Auto IV, as seen in a beta screenshot.

Description
The Revolver is the most accurate pistol in the GTA series.It also shares the record for being the most powerful pistol with the Desert Eagle, although the Desert Eagle edges it out, being a .50AE instead of a .357.

GTA Vice City

The Revolver is known as the Colt Python in the original PS2 version of the game and .357 in all other versions. It is based of the Colt Python and is available to the player on Vice City's second island Ammu-Nation for $2,000, spawnable in Vercetti Estate, and discoverable in several locations. The high cost of the revolver (compared to the M1911's modest $200 price tag) comes with the reward of it being almost guaranteed to kill any target with a single shot. However, the gun cannot be fired while running, and must be fired from a Weaver position (grasping the butt of the gun with the right hand, then cradling the right hand and gun with the cupped left hand, all while planting feet at a wide stance) due to the heavy recoil of the .357 Magnum cartridge. It also has a moderate cylinder capacity of 6 shots, making it excellent against small groups.

GTA Liberty City Stories

The Revolver in Liberty City Stories and is once again based of the Colt Python but called .357 in-game it cannot be bought from Ammu-Nation and so it can only be found in spawn locations.

GTA Vice City Stories

In Grand Theft Auto: Vice City Stories the revolver once again is a Colt Python, named Equalizer in-game, but  features a laser scope and a 6 round barrel, although the scope cannot be used.

GTA Chinatown Wars

The Revolver is also a weapon in Grand Theft Auto: Chinatown Wars, and was named the Revolver in-game. Although it cannot be visibly seen in the game the HUD can be seen on the touch screen and on the Ammu-Nation website and resembles a snub-nosed .38 Smith and Wesson or a Colt Detective Special).

Trivia

 * Rockstar Games renamed the Colt Python to .357 in later versions of GTA Vice City, possibly to avoid copyright and trademark infringements.
 * The Colt Python is called ".357" in GTA Liberty City Stories, and the GTA Vice City Stories refers to the gun as Equalizer.
 * It was originally going to be featured in Grand Theft Auto IV, as seen in a beta screenshot.
 * In GTA Liberty City Stories, the spent shells are ejected while firing, which is impossible for any revolver.
 * Though the weapon itself doesn't appear in GTA San Andreas, the model from GTA Vice City is used for the giant Python at the entrance of the Los Santos Ammu-Nation.
 * The name Equalizer may be a reference to the Modesty Blaise comic "Top Traitor" as Modesty hands Tarrant a gun of similar model she mentions it will be a great equaliser.
 * The scope on the python in GTA Vice City Stories may be visually inspired from a gun used in the movie "Terminator" also set in 1984 although the movie was in Los Angeles not Miami (Vice City).
