Al, yes you are right about the switch, it is indeed on the side towards the back of the light. It is made obviously tougher with thicker aluminium in nearly all places that I can observe. The sales person told me that it was the only one they had left over from an order for a local security company. In any case, it looks pretty cool and I'm glad to have it in my collection now! The surefire box it came in is another story in itself. The box looks completely different to any surefire box I've seen and the inside didn't have any packaging to stop the light from moving around. And the battery was a single stick which I believe SF uses in some of it's weapon lights prone to heavy recoil.
