I'm going to have to bite the bullet and get a TLR light with laser for my Mossberg 590. The separate laser and light setup I had was clunky and after a few shots quit working. However, for the HD setup it's intended for says there needs to be separate controls for both the laser and the light, independant of each other. Can't find a thing on the web that says that Streamlight's coil switch can operate both separately. Can I get some enlightenment? Any alternatives to the TLR that are worth looking into?
