Has anybody had a chance to mess with the shotgun light from Streamlight? Looks nice, and should be a fairly easy install on my mossy 500, but is it worth the price? I could easily get a gg&g, elzetta or other mount and just run a SF G2 with Malkoff for abou the same price. I do like the more stream-lined package of the foreend light that the TL Racker offers, though.
