Call me a skeptic, but is seems like you would be able to see the gun if he was shooting with his right and holding the camera with the left, unless he was shooting from the hip.
Too funny!I could do that.......if I could shoot that good??
I saw that episode of the Rifleman. Do you remember it? Wasn't it with Sammy Davis Jr. He was a gunslinger who couldn't shoot anymore but the Rifleman hid nearby when Sammy did a shooting demonstration and scared off the gunslinger who was going to challenge him.
Same thing here.
