+1 on the Streamlight TLR-4. I originaly was getting the TLR-3, but I upsold myself to the TLR-4 which has the added laser and is a bit brighter. The TLR-4 has more of a natural fit on my M&P 40C. It can fit on just about anything. So, I really like that.
I think they are at least assembled in the USA. Packaging says " Assembled in the U.S. from foreign and domestics parts."
I would turn the light on, but I don't want to temporarily blind you
