Great product, with a few quirks.
I love the Surefire! It is a bit bulky, but that's part of the design philosophy. I think they could reduce the dimensions slightly, but kept it the same so that it would be compatible with old Surefire X300 holsters. If I had to change anything, it'd be the switch design. I'll likely pick up some PHLster XL switches as the OEM ones are hard to hit with my smaller hands. The momentary on (push in) is uncomfortable, I would need to build a callous so it doesn't bruise my thumb. I can't hit the switches on the strong hand with my index finger and if I flip the switch down with my thumb on my support hand I have to break my grip to turn the switch back off. So far the button switches seem to work the best for me, these switches are less than ideal for my hands but very sturdy.
The light is bright, with a nice hotspot and it throws a lot of light outside of the hotspot, giving you target focused illumination in conjunction with greater situational awareness.
