That Gun

That Gun is a unique weapon in Fallout: New Vegas.

Characteristics
That Gun is a futuristic-styled revolver that fires 5.56mm rounds, and is the successor to the .223 pistol from Fallout and Fallout 2, it weighs a hefty 5 pounds and has a motorized cylinder and crane for quicker shooting and reloading than a typical revolver. It has the unique capability of using dedicated armor piercing rounds, something that no other pistol in the game is capable of.

That Gun can be repaired using weapon repair kits, merchants, or any other non-energy pistol with the jury rigging perk. Along with Lucky, it has the highest potential critical hit chance (95%) of all one handed non-energy guns.

Location
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 may be picked. The key may also be purchased during the quest Come Fly With Me.

Bugs

 * If loading a saved game from the main menu in which you have That Gun 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.
 * Variations of the 5.56mm rounds do not seem to load in the Honest Hearts add-on.

Behind the scenes

 * According to J.E. Sawyer, its name is derived from the fact that many players referred to the .223 pistol as "That Gun from Fallout and Fallout 2."
 * Like the .223 pistol, That Gun is modeled on the pistol 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.
