That Gun

That Gun is a unique weapon in Fallout: New Vegas. It is a futuristic-styled revolver that fires 5.56mm caliber ammunition, and is the successor to the .223 pistol, though its effectiveness has been considerably reduced compared to the earlier titles.

Characteristics
"That Gun" can be repaired using only Weapon Repair Kits or by making a trader repair it. Or, if you have the perk Jury Rigging, it can be repaired with almost any other pistol. It also has a small green light on the side that turns yellow when you reload accompanied by the sound effect of a capacitor charging. This weapon requires a Strength of 6 or higher to be wielded most effectively. It also benefits from the Cowboy perk.

Locations
It's located in Novac, inside the Dino Bite Gift Shop. It can be purchased from Cliff Briscoe, or, if you prefer, stolen from the storage room. It is on the end of the first shelf loaded with Souvenir Rockets to the right. The storage room key can be pick-pocketed or the lock (Very Easy) may be picked. The key may also be purchased during the quest Come Fly With Me.

Behind the Scenes

 * According to Josh Sawyer, its name is derived from the fact that players referred to it as "That Gun from Fallout and Fallout 2."
 * Like the .223 pistol, it is modeled on a gun used by Rick Deckard, the main character of the film Blade Runner. This version differs, however, in that it has one trigger instead of two and a generally more weathered and rounded look. It can also fire .223 rounds, though 5.56mm is the default of which .223 is a variant.
