I actually filed down the rear edge of the Pawl. Did I take off too much? No. I verified that by making sure there is no way to pull the trigger or cock the hammer when the cylinder is not latched. The top of the pawl presses onto the cylinder latch if the cylinder is not completely latched.
I took my Service Six out and shot 150 rounds without any jams. I would always shoot all 6 shots before setting my gun down or doing anything that would move the pawl.
Previously it used to be such a pain to point the gun up and cock the hammer in single action mode before each shot.
Shouldn't have to file like that but it works with no safety issues or side affects.
You may wonder why they they are worried about someone pulling the trigger when the cylinder is out. The only time this would be an issue is when the cylinder is almost all the way in but not latched. Only then could the firing pin hit the primer.
