i wouldnt know to do that (i dont own any guns)Ask any gun owner what they would do if somebody handed them a revolver and told them it was unloaded.
The answer is simple. You would take the gun and point it down and away from yourself and anything else. You would open the cylinder and inspect it for any rounds and then you would look down the barrel to see if there was a round in it.
Short of doing this you shouldn't be holding a gun.
Sadly a lot of people have been shot with guns that "weren't loaded"
this is a unique case. hes instructed to have the gun.
