Just picked up a sure fire DF fury tactical and I LOVE IT! Coming from a Streamlight HLX and an OLIGHT M2R Warrior Pro I’m loving the Surefire DF more than anything else. It’s big enough to use as a bludgeoning tool, but small enough like the HLX where it doesn’t take up too much pocket room. This new Thyrm DF Switchback is AWESOME!! I would not operate this light without one that’s how good it is. The clip is awesome, the button pushing is much easier than the HLX with the switchback on, and the size isn’t too obtrusive. I also wanted to say, with a little oring added, this DF switchback WILL ALSO fit the Olight M2R Warrior Pro (something I thought was a huge downside when using that light that it didn’t have a a way to mount a switchback. Well the DF solves that problem! Thanks Thyrm!
