This is an amazingly small, amazingly bright weapon mounted tactical flashlight. The Streamlight TLR-3 is a compact LED light that you can mount on most guns but specifically designed with small compact or sub-compact handguns in mind. I use this with my full size Smith&Wesson M&P 9mm for home defense and it fits great! The light doesn't extend much past the front of the gun which reduces its exposure to lead build-up, muzzle blast shock and of course accidental bumps. At a fraction of the cost of Surefire lights and even other Streamlight models this TLR-3 is a mini power house with a lot of bang for your buck. Thank you Nutnfancy for the recommendation and BotachTactical.com for the great deal and fast service! (less info)
