My revolver, by contrast, came with a heavy six plus pound single action with the double action pulling through at almost twelve pounds. The trigger pull was not consistent one chamber to the next. I carefully removed the side plate and took one coil off the trigger return spring. – No other modifications were made. This caused an immediate drop in single action release to four and a half pounds with positive trigger reset. After firing approximately 300 rounds, the single action pull has settled in at about three and a half pounds and the double action is a smooth ten pounds, eight ounces. The action now exhibits the famous S&W crisp trigger release, smooth functioning and hitch-free double action delivery.
