- 4 to 7 casings can be found on the dead body of an enemy that was wielding a 9mm submachine gun or a 9mm pistol at the time of their death. Powder Gangers, Crimson Caravan guards and mercenaries typically carry both weapons. Great Khans occasionally carry 9mm submachine guns.
- When you fire a weapon chambered in the 9mm round, there is a 25% chance you'll get a casing and a 20% you'll get a casing if you're using the +p round.
- You'll get 25 9mm casings if you buy a 9mm case box.
- Occasionally some traveling merchants will "sell" 9mm casings (among many other calibers), but they will always be for free. Likewise, if you try and sell casings to a merchant, you will not yield any money.
- Can be looted from many Powder Gangers.
