Popular for good reason - Streamlight TLR-2G LED Rail-Mounted Tactical Light

Have 3 TLR-2s and am more than satisfied. A red one sits on my home defense KSG shotgun and a green one on my wife's MPX-K-PSB. Different colors so we can clearly identify who's dot is whose. The other green is on my MPX carbine coach gun. First job in the dark is identifying friend or foe, easily done at self defense engagement ranges with that bright light!! If foe, second job is to then engage the threat. When zeroed for CQB, the lasers are never more than 1.5 inches off point of impact - much more accurate than aiming through a sight when adrenalin grabs me. On these three weapons the TLR-2 is easy to mount where the foregrip hand can control the light with a flick of the thumb. I must admit that while the red is quite adequate for CQB, the green is much easier to see with our very senior eyes.
