My Streamlight TLR-2 is a bit large for my recently acquired M&P40c.

Laserlyte makes some products that will fit a subcompact rail but they don't seem to have many reviews at all, and their light is just 3 LEDs w/out any kind of reflector.

My primary question is whether laserlyte can be quickly removed like (I assume) the Insight X2 can?
A light or laser mounted on the rail won't fit in the holster, so being able to quickly slide it off is a must.

What other options are there?
I saw aimpoint makes a tac light "glove", which might be a possible option.

Thoughts? Opinions?
