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. That Gun benefits from Cowboy.

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, That Gun is modeled on the revolver 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 more weathered look. That Gun can also fire .223 rounds.
 * 5.56mm rounds are the same size as .223 rounds
