In my article on “Should, you use a gun mounted light?” I concluded that “most professional have and use both a handheld and gun-mounted tactical light”. I also review the pros and cons of a gun mounted light. Finally, I conclude “That gun mounted lights, even with the understanding and acceptance of certain negatives, are not only recommended but even required gear for home handgun defensive use.”
Here is my top pick for the Best Gun Mounted Lights
This is the only mounted light, that I've found, that not only is powerful enough, at 800 lumens but includes an easily accessible strobe and control paddles that operate ambidextrously and easily in all three modes – momentary, permanent and strobe. Finally, it's also at a better price point that a number of other lights.
I have a hands-on YouTube video which analyzes both the Streamlight TLR-1 HL and the Surefire x300 Ultra. Both have top quality components and work well on most handguns. Check out the video, however, to see why the Streamlight is recommended.
Always be prepared, be well.
