James, as you are aware, there are two cylinder stops on your double action. There is one that is coil spring activated and is mounted in the trigger. Often this stop is gunked up with congealed oil. To un-stick; remove the trigger and soak with penetrating oil. It may be necessary to apply heat from a hair drier. The stop and spring are in a blind hole so it is a bugger to free up. Good luck.
