After having cleared a few buildings using simunitions and live guns(answering alarm calls on patrol with my Dept.) I have an observation to make. While I do not have a weapon mounted light on my duty Glock (eventhough it has rails) I can see the usefulness of one. For me I have enough on my belt already without another light. I do carry two flashlights though.... A surefire G2 with P61 lamp assembly (120lumen) for clearing buildings and the like and a Streamlight Stinger XT rechargeable for the rest of my tasks. The blinding light of the surefire is great when I've used it in simunitions training. Shining in the eyes of an opponent in the dark not only temp blinds them, but destroys their night vision for multiple minutes. However the bright light if reflected off of windows or white walls can have the same effect for you!! We firefly them off the floor, and move while dark to minimize this effect, and the corona of light around the main beam is more than sufficient to illuminate your path.
The real reason for my post is to say this though..... When doing this training it becomes very obvious, when hit with rounds that everyone instinctively shoots at the light! We train to keep the lights out to the side away from the body to minimize the chances of getting hit in reality. Do not search with a light by your head, straight in front (center mass), etc. As you present a glowing bobbing target! This is the problem with a weapon mounted light. You are behind the weapon! However once you have identified your target, you may elect to tranfer to your weapon mounted light, or one of the two handed holds (rogers/surefire).
To stress this point, we had an officer shot in the line of duty on a traffic stop a few years back. He was shot in the eye, while approaching the vehicle. He had his flashlight beside his head illuminating the back seat, when the suspects shot at the light, striking him in the face! To his credit he returned fire, wounding one of the occupants and then gave chase, before terminating pursuit when backup arrived!
Sorry this is so long, but I feel that this is an important topic, which deserves serious disscussion.
