I don't know if I have ever blogged about the Glock OEM Tac Light before I should have. I love this light.
"If you are looking for a good light for your Glock, then look no
further. This light is tough, and very light. When mounted on a Glock
pistol, you can barely feel a difference in weight versus not having a
light. This light is produced by Glock and is constructed of the same
polymer as their pistol frames."
This is designed for the Glocks. I use it on both my Glock 17 and 21 with equal utility. Now on Amazon Prime for $79.
Click the image and read the Comments! Great stuff.
There are brighter lights but I feel like this is perfect for the job!
--Works great with suppressors in the dark...
