I see a LOT of guys asking for the rail-type weapons. I too ask the very same question. "why do you want it? Is it cecause it looks good? or is it because you saw it in the movies. Personally, I can't see why they want to place a light on the rail. I tell them the BG is gonna see THEM BEFORE THEY SEE THE BG. I get the response. "well, it looks good" I ask em "where do you think you'll get a good carry holster?" and they have no clue. The light looks real nice, in the movies, but in real life, I'll choose to place the light away from my body, should that BG have a weapon, and try to shoot out that bulb in the light, thinking it's my head behind it.
BTW, Insight Technology is about 6 miles from my home where they make all that good stuff. They're plant is in Londonderry NH
