I seem to remember reading that it is impossible to hit anything firing double action. Maybe not true?
It is likely more true for most of the people who buy double actions and then shoot them mostly single-action. Then there are those of us who remove the hammer spur and shoot them as they are intended. Having just finished with Jordan's book, "No Second Place Winner", I noticed that there were several pictures of his gun without a spur on the hammer. He was the one who shot aspirins.
