I would recommend this item to a friend.

I have a M910 on my Duty Rifle. It came with a 150 Lumen beam. I swapped the head of the original with this and it now puts out 700 Lumens... It's almost "Too" bright. It is something that within the distances inside of a home or even the typical yard you would not want to try to look past the light for a shot. In a tactical situation I would strongly recommend it. On the range, guys 3 stalls either side didn't need to use their own lights.
Cons:Almost too bright... It will back light... I'll adjust and keep it.
