I went with the SureFire 6P Defender with a larue mount. It works well. I don't have the pressure switch cuz mine is mounted just infront of the VFG. I use my knuckle to turn it on and off. I know that isn't the best method, but i am being cheap right now and not getting the pressure switch. I believe you can get them online at almost any place they sell SureFire. I like the light cuz it has a jagged bevel. Hope this helps. And that thread was under Photo Gallery "Evil black guns" if you wanna peep mine.
