I guess I'm missing something. To the best of my knowledge NO ONE is advocating lowering the hammer on a cap and carrying the revolver in that manner. So, the face of the hammer has a groove that is lowered on the pin in between the chambers, so the hammer isn't on a cap. You can beat on the hammer all day- there is no cap under it.
The next situation is to pull back on the hammer, rotate the cylinder enough to bring the NEXT chamber into alignment but before the hammer cocks it slips off whatever is grabbing it and drops on the loaded chamber. I get the impression folks are saying this is more likely if the hammer is in between the chambers. Whether the hammer is initially on an empty chamber or initially half way in between the two chambers, in order for the cylinder to rotate far enough to drop the hammer on the next chamber with a cap, the hand (operating off the hammer) must move upward until at the top of its path and the bolt locks up the cylinder. Whether you start from an empty chamber or half way in between, the hammer must still be pulled back THE SAME AMOUNT, in order to lock up the gun on the next chamber.
So....let us examine the SAFE practice of the hammer on an EMPTY chamber. The next chamber is to be loaded. Now let's suppose the gun's hammer (while in a holster) grabs against your coat cuff or a branch, or anything that draws the hammer back to almost full cock and then the hammer falls on the next chamber that is loaded and fires. THAT'S with the hammer INITIALLY on an EMPTY chamber. If the hammer is in between two chambers, on a pin, and the same thing happens, (the hammer accidentally drawn back and drops on the next chamber, loaded and capped) it is the same thing. I don't understand why some folks reason lowering a hammer half way between two chambers is unsafe versus lowering on an empty chamber.
As I said, maybe I'm simply missing something-been known to happen :hmm:
