Stays on for about a minute or 2.

Super easy install and they seem to be very sturdy. A very modular set up for fast and easy install.

Fit is perfect, quality is top tier. It fits very snuggly to the trigger guard as well. Multiple holsters and cleanings. It is just as snug as the first day.

It fits my glock 43x perfectly. The lumens or what to expect from a small light. Fit both my glock 42 and 43x, real bright.

Streamlight customer service is worthless. Makes me hesitant to buy more of their products. Same issue.

The battery life of this light is very limited. When in momentary on, if i ease up on any amount of pressure the light just turns off. I have to order special lithium batteries from amazon to get the light to work.
