Lock and Load is a shop in Paradise Falls, run by Pronto. The shop has a very limited supply of anything, and everything it does have is in very poor condition. Typically the store's owner, Pronto, only has around 150 to 400 caps on him at the very most. His repair skill is also very low. The only way to improve his inventory is to "invest" in Lock and Load by completing the Economics of Violence unmarked quest. This will not, however, improve Pronto's repair skill. After investing, the quality of the goods rises significantly.
Inside the Lock and Load, you will find one workbench to the inner-left corner. The counter is littered with weapons. Behind the counter is the locker that holds Lock and Load's inventory, which requires a key to open, as well as two owned ammunition boxes sitting on the floor. Another owned ammunition box is on the desk next to the counter. To the left of the main counter, you can see a cage containing a skeleton equipped with a party hat with a plate in front of it.
The door which can be opened takes you to the basement where Pronto sleeps.
