If you are going to shoot double action and want a stop to hit just before the trigger brakes and fires double action a lot of combat and action shooters used to take a pencil eraser and super glue to the frame behind the trigger andthen take an emery board and dress it down until it will rotate the cylinder and stop then with just a little more pull on the trigger it will fire. A very easy way to find out if you really want a stop. Jeff
