Do you carry a handgun for self-defense? If so, carry a good flashlight. The statistics indicate approximately 60 percent of all confrontations occur in dim light conditions. That does not necessarily mean complete darkness, but rather diminished lighting to the point where your ability to identify the threat is jeopardized. You are responsible for knowing what you’re shooting at and for every round that leaves the muzzle.
Just like a good blade, there are many other reasons defensive-minded folks may want to carry a good light. Defensive strikes, a disorienting strobe, navigation and signaling all come to mind aside from threat identification. High quality pocket carry lights with variable brightness and strobe features are widely available today. There’s no reason not to carry one.
For most, the thought of holding a light and shooting is a daunting thought. Yes, there are weapon-mounted lights and lasers (lasers do not allow for identification), but there are some distinct advantages of a handheld light. One is that you can use a handheld light to search and identify without having to muzzle everyone. This would not be the case with a weapon-mounted light system. Weapon-mounted lights have their place, but you should carry a handheld, as well.
