First click of hammer leaving the frame = safe position
Second click = cylinder spin, load position
Third click = I don't know
Fourth click = all the way back and ready for BANG
With the loading gate open, and the hammer in load position, insert one, rotate and skip one, then load next four holes.
POINT IN SAFE POSITION, pull hammer back all the way to BANG position, squeaze trigger while holding hammer at rearward position and allow the hammer to foward while holding it. DO NOT let go of trigger untill the hammer is all the way foward. The hammer should be on an empty chamber.
I strongly sugguest getting a LOT of practice before using LIVE ammo.
On a side note, I had a revolver get stolen years ago. When I finally located the POScum that stole and sold it, I asked why he sold it. He said it was broken because the double action didn't work and to load it was a big problem.
