Actually, I'm cribbing from Bill Murphy, one of the guys who refined the SureFire techniques and IMHO one of the best firearms trainers on earth, and John Meyer, formerly of the H-K training cadre and now head of Team One Network training, who has been refining low-light training for Streamlight. BTW, my original low-light training was with Bill Rogers when we were still using Mini-MagLites. A lot of the wepons' mounted light training was developed for and evolved from law enforcement and, again IMHO, not applicable for non-LEO application.
My recommendation — and my practice — is that the weapon mounted light is the secondary light source. The primary light source is always a hand-held light for the reasons outlined by Mike and Rob:
• The light gets shot at. It's probably helpful if the light isn't positioned in front of your heart...
• A weapon mounted light means the muzzle of the gun goes where the light goes, and — correct me if I'm wrong — but we don't want to point the gun at anything we're not willing to kill or destroy, such as a child, your new 90-inch plasma or even Fluffy the Hamster.
• A weapon mounted light lacks the search versatility of a handheld light.
Still, a weapon mounted light is a great advantage for several reasons:
• When things go bump in the night, you only have to grab one thing if the light's on the gun...if necessary (and, no, it shouldn't be), you can flick on the gun light to find the handheld light.
• In the Real World it's conceivable you might need one of your hands for something important, such as staying in physical contact with or restraining a child or Spousal Unit, punching in 911, holding a door open or pushing aside a piece of furniture...a weapon mount light gives you the option of using one of your hands without compromising your tactical situation.
• A weapon mount light is the perfect tool if you as a civilian find it necessary to hold a aggressor at gunpoint while waiting for the police. Ideally, you've got the aggressor laying flat on the floor, arms spread wide, legs spread and eyes looking AWAY from you (the intent here is to minimize your risk of the aggressor being able to resume the attack). You may need to be on the phone with the police at this point. The weapon mount light should be ON (even if the room lights are on), with the gun pointed AT THE FLOOR slightly away from the aggressor...should the aggressor make a move you can quickly index the gun/light onto the aggressor's eyes.
John Meyer quite correctly took me to task for saying we should cover an unarmed aggressor on the ground with the gun/light (back to that Rule thingie); however, if I am in that situation the gun/light remans on the aggressor's face until he/she is spread-eagled down and looking away. Only then does the gun come off the threat, but NOT very far off the threat.
