This has more information from what is a trusted source.

He said the prop gun was one of three on a cart outside a building. One of them was taken by the assistant director on the movie who went inside and handed it to Baldwin.

"As the assistant director handed the gun to the actor Alec Baldwin, (he) yelled 'cold gun', indicating the prop gun did not have any live rounds," the affidavit said.

As the investigation proceeded, questions were raised about working conditions on the set of "Rust", a small budget Western movie of which Baldwin was both star and a co-producer.
