Streamlight ProTac 2.0: Compact Handheld Light

Having a weapon-mounted light on your defensive-use gun is a good idea, but it’s also wise to have a handheld flashlight available. Streamlight covers both those bases, and their ProTac 2.0 is a fantastic example of a compact, easily recharged handheld light. The ProTac 2.0 is small enough to carry in your pocket but powerful enough to identify potential threats. And it comes with the Streamlight name behind it, so you can be confident in its quality.
