Rick Deckard carried a handgun while working as a Blade Runner in November 2019.
He used the gun to retire Zhora and dropped it shortly after, when he was attacked by Leon. Rachael picked it up and saved Deckard by shooting Leon in the head, killing him.[1]
Deckard still had the gun in 2049 while hiding in Las Vegas.[2]
Behind the scenes
Concept art by Syd Mead
The prop used in Blade Runner was constructed from parts of a Charter Arms Bulldog revolver and a Steyr Mannlicher .222 Model SL rifle. The prop was re-created for Blade Runner 2049, as the original had been sold to a collector for $250,000. In all, four were made for 2049, three containing actual weaponry, and one made of rubber for action scenes.[3]
In the novel Do Androids Dream of Electric Sheep?, Deckard uses a laser tube.
