We highly recommend Streamlight Flashlights for home or street defense.   LED technology has advanced so much in recent years that it truely is time to clear out your old flashlights and replace your home and travelling white lights.  The TLR-1 is one of biggest selling handgun tactical lights and is easy to mount and easy to use.  If you are looking for a light and laser combo, the TLR-2 tac-light is what you’re looking for.   The Streamlight Scorpion PolyTac is a good companion for travelling or for mounting on your M4 Carbine.   I highly recommend doing some training with weapon mounted flashlights and using a flashlight in your hand and firing a handgun.

When you are looking to mount a flashlight, I think it is worth considering if you are going to be CCW this weapon or just leaving it at home in a safe.   I suggest that CCW should be low key, and putting a light on a gun is going to mean using a specific holster for the gun which will add bulk and limit the ways you will be able to carry.   Carrying a Streamlight flashlight in your pocket or jacket is easy, especially if you are wearing a good CCW vest or jacket like Eotac wear securing spare magazine or knives and flashlights is easily done.
