|For an overview of .223 pistols, see .223 pistol.|
That Gun is a heavily modified, pared down .223 pistol, successor to the same weapon from Fallout and Fallout 2. The weapon weighs 5 pounds and has a motorized cylinder and crane for quicker shooting and reloading than a typical revolver. When reloading, the weapon's cylinder mechanically swings open to the left and auto-ejects the spent casings. The green light on the left side of the gun turns yellow while reloading and then turns green while making a ringing noise once the weapon has reloaded.
Until the release of the add-on Gun Runners' Arsenal, That Gun was the only pistol capable of using dedicated armor piercing rounds. That Gun is also the least expensive, named rare gun that is available for purchase in Fallout: New Vegas.
That Gun can fire about 1120 standard rounds, the equivalent of 224 reloads, from full condition before breaking.

The weapon is located in Novac, inside the Dino Bite gift shop. It can either be purchased from Cliff Briscoe or stolen from the storage room. It is on the end of the first shelf with the rocket souvenirs to the right. The storage room key can be pick-pocketed or alternatively the Very Easy lock can be picked. The key may also be purchased during the quest Come Fly With Me or any time after its completion.
- Along with Lucky, it has the second highest potential critical hit chance multiplier (x2.5) of all one-handed non-energy guns, after the silenced .22 pistol.
- If it is stolen and Cliff Briscoe witnesses the act, he will retrieve it, possibly causing the gun to become unobtainable.
- Using this weapon against super mutants counts towards the Vault 13's Revenge challenge.
- Using this weapon against robots counts towards the Benefit Or a Hazard challenge.
- The Vault Boy icon differs from the 5.56mm pistol's icon, despite no major model change, other than the weapon's finish and LED color.
- That Gun is difficult to repair, as outside of the perk Jury Rigging, no other weapons are in its repair list apart from the Gun Runners' Arsenal 5.56mm pistol, which can only be found at vendors. This means that the only ways to repair That Gun without the add-on or perk are vendors with item repair abilities or weapon repair kits.
Behind the scenes
- Like the 5.56mm pistol and the .223 pistol before it, That Gun is modeled on the pistol used by Rick Deckard in the film Blade Runner. This version differs considerably in proportions, and lacks the bolt handle, ejection port, and second trigger. That Gun and the 5.56mm pistol being used to destroy 15 robots for the Benefit Or a Hazard challenge is a further reference to the film.
- According to Joshua Sawyer, its name is derived from the fact that many players referred to the .223 pistol as "That Gun" in Fallout and Fallout 2. 
- Cliff Briscoe may still sell it in his shop, creating the possibility of obtaining a second weapon. [verified] If That Gun is stolen from the storage room,
- If loading a saved game from the main menu in which That Gun is equipped and drawn, the reload animation takes twice as long as normal. This can be solved by simply switching to another gun and then back again. [verified]
- The Professional perk. Curiously, its non-unique counterpart, the 5.56mm pistol, is. [verified] That Gun is not affected by
- Courier's shoulders, but the gun will stay in the same spot, causing it to careen to the right and left. One's head can even be moved backwards, to the point of seeing the viewmodel hands. [verified] Rarely, when aiming down the sights of That Gun, when turning right or left the camera will instead pivot from the
