I have an M+P9 VTAC and was looking for a weapon light that would match the dark earth frame. I selected an Insight M3 Tactical Iluminator. My MK25 wears a Streamlight TLR4. I had a TLR1 mounted and found it was a bit chunky. The TLR4 is the compact model with laser and one battery, light and looks great!
Thanks for that yohann, where was that when I pulled the trigger on the Insight!
Check out the TLR-3I have been looking for one for the M&P as well. But one that doesn't protrude beyond the front of the barrel.
