Ballistic Fist

The ballistic fist is a weapon in Fallout: New Vegas. It is the most powerful of all unarmed weapons in the game. Max Str and unarmed can bring this weapon to 114 damage.

Characteristics
The ballistic fist is a gauntlet with a small, pressure plate-activated shotgun welded to it. When using full armor suits, like the T-51b power armor, The shotgun appears to be grafted or welded to the suit, unlike the Displacer Glove or Pushy, which appear to overlap.

The ballistic fist is similar to the punch gun found in Fallout Tactics. It is an unarmed weapon rather than a Firearms weapon.

It does not require ammunition.

Locations
The Praetorian Guard, Caesar's personal bodyguards, hold them. They can be found in The Fort, inside Caesar's tent. Additionally, there are a few of them in Legate's Camp, however you can only get to the location at the end of the game and thus can not be brought out of the quest area for main game use.

Can be purchased from Torres in the Hidden Valley Bunker and from the quartermaster in the Hoover Dam offices after gaining access to their respective inventories.

Can also be purchased from Blake of the Crimson Caravan at the Crimson Caravan Company location.

However, if you happen to turn upon Caesar and kill him, you can obtain one from him. Be prepared for a nasty, prolonged fight with his Praetorian Guard, etc. afterward. Consider fighting your way out of the compound and coming back later for more items if/when you defeat additional members of Caesar's Legion. Bring lots of stimpaks and ammunition!

If you take Boone with you into The Fort he will acquire and equip for himself the Ballistic Fist (presumably Caesar's)
