spoiler:

Seperate each of the bags into pairs. Weigh each in your hand. If you think you've got a pair with a real bag of gold, you weigh them

spoiler:

You fix the scale

spoiler:

you replace the scale

spoiler:

You add a bag onto each side of the scale. Once it starts tipping, the bag you put on is the gold.

spoiler:

You keep adding onto the scale. Once it says .1, the bag you put on is the gold.

spoiler:

You take a one bag off at a time. Once the .1 is gone, the bag you took off is the gold.

spoiler:

You look inside each bag for the real gold [:D]

spoiler:

You do nothing with the scale...

spoiler:

You put the bag that says 1 and the bag that says 10 on the scale.

spoiler:

Stop imagining

spoiler:

considering its a revolver you can see practically all of the bullets because on each side it shows 3 bullets(considering half a bullet is still one bullet.)so practically the man with the gun knows whats going to happen if you say"fire away".but if you spin,they wont know unti the chambers stop.So id say he placed them adjacently to make sure that this moment would happen.Since your practically in a state of shock,youd probably think rite away that the bullets arent going to hit you.but that wasnt the actual vital information.it was that he placed them adjacently.he could have hit a spot that was clearly far away from the bullets,or he could have shot in the dead center between the bullets.so actually youd have a less chance of getting shot if you had spun it again.
