I haven't found any recent discussion on this topic, but I think there is a simple fix to this problem. In the past several people on the forum have mentioned that, if you twist your flashlight a certain way, the hook that Surefire provides with its lanyards will release from the wire ring that is around the barrel of the flashlight. I have experienced this problem myself, and it can occur regardless of whether the pocket clip is on the flashlight or not.
A simple way to prevent this is to attach a 3/4" split ring (split key ring) on the wire ring that goes around the barrel of the flashlight. A split ring that is this diameter or larger can't push the hook's gate open. Note the split ring can be darkened by putting it in the cold blue that is used to blue small gun parts.
