How do you uncock a revolver?

Answer 1

If you have no idea what you are doing find someone else who does.

First, point the gun in a safe direction. Make sure it is not pointed at any body part of yours or anyone else. Ground is best.

If there is enough room between hammer and the frame place a finger of your off hand on the hammer (NOT on the frame, a falling hammer might hurt and an older one with a firing pin on it will draw blood).

Hold the hammer with your thumb and pull the trigger, then let the hammer down slowly.

Be careful, on some older revolvers there is no safety mechanism that prevents a shot when the trigger is not all the way back and a falling hammer will make it fire. Don't decock a revolver when your fingers are wet or greasy.
