Where might I buy a toy wild west gun like Indiana Jones has?

Question

The kind with the curvy handle that was used in the wild west. Just like the kind Indiana Jones had and the kind like what Marty from Back to the future got when he went back to the Wild West. I'm making a movie and need props. I don't want to buy online so if you name a store (not online) you will most likely get best answer! This isn't necessary, but preferably the toy gun will have the trigger be able to be pressed and (also not necessary) hopefully it might make a sound as if I actually shot it.

Answer 1

Indiana Jones had a WWI Enfield Revolver.

Toy guns are apparently verboten these days

Answer 2

A dollar store.

Seriously, thats like THE easiest and most mass-prosuced toy in the world to find.

Answer 3

Walmart
