Well, here's the trick with that. There are so many rail mounted lights, lasers, and combinations of the two on the market, that you're pretty much stuck with a custom molded holster based on your specific weapon configuration, if you want a glove-like fit. I do use a rail light on my PPQ at home. I have one that I can disconnect with a spring loaded attachment, so I can put it on and take it off in a second. If I wear it holstered, I take the light off. I reserve the light mainly for bedside use. I have a Beretta Nano with a laser, but since only two companies make a laser for it (CT and LM) it's easier to find holsters pre-formed for that one.
