Best light for the price - Streamlight TLR-1 HL CR123A LED Rail-Mounted Tactical Flashlight

I have been using this light for over a year. I have not been kind to it and I use it on my G19X. The light stands out futher than the muzzle of the barrel. This has caused hot gasses to discolor the section of the housing just below the muzzle. It has not impacted how bright and dependable my light is. I have banged it against metal, wood. You name it. It has dings and scratches but it keeps on going. Anytime the glass gets dirty I just use a cotton ball and Vaseline and cleans it right up. Only negative and it's not that big of a deal. When mounted on a glock even with the hardware provided there's a bit of wiggle unless its crancked down very hard. But that's typical with any glock mounted weapon. It has strobe and constant function. If you do not like the strobe you can turn it off by clicking the momentary switch 9 times and holding it on the 10th until the light turns off.
