Proper light discipline is important when you are using the laser.
The laser is not an intimidation device.
It is not a target identification device.
It is simply another set of sights for your handgun, an alternative sighting device that works best in challenging low light situations.
It is designed to be turned on at the very moment you raise the gun to the target to fire.
It is not designed to be turned on in advance of that moment.
If you turn it on in advance of that brief moment, you're doing it wrong.
If you try to use the laser in ways it is not designed, you're going to be disappointed at best. If you fail to develop good light discipline, you might be worse than disappointed.
But it won't be the laser's fault.
