This light fits the Hellcat well; switching to three different modes (from laser/light/laser-light) is simple by holding the button. The light is bright in low-light conditions but isn't blinding. My only complaint is that my fingers are slightly too short to reach the activation button. I have to stretch my finger or use my off hand. Maybe I am holding the support hand correctly. I don't have large hands but also don't have small hands - for reference, I wear large-sized nitrile gloves comfortably while fitting into medium-sized (for finer work such as soldering). This is more genetics but for a compact weapon and for possibly smaller people who may want to use this on the excellent Hellcat, just be aware.

Best light for the hellcat! IMO
