Thanks for the very informative post. I debated on whether or not to get night sights ($100 over standard sight), a tactical light w/ laser ($300 and up locally), or go with standard sights and a flashlight. I read threads that gave mixed reviews of lights and lasers strong and weak points.
In the end I opted for night sights and strategically placing battery operated night lights to illuminate areas a BG might enter or travel through. I figured night lights should provide sufficient light to identify a target and the night sights should help acquire a good sight picture without having to use a flashlight that might give away my position. Of course the bright flash and loud noise will be a good indicator after the first trigger pull
