This is exactly what I was hoping to get for my Glock 22 (40 cal). It fits nicely under the barrel and does not extend beyond like some other light/laser combinations at which I looked. The light and laser are powerful enough for the range in which they will be used.
Pros: Compact and easy to operate with the side buttons.
Cons: A little bit confusing to set up the default laser/flashlight, but that is mainly my fault.
