Pair this with the cloud defensive mount - SureFire Scout Light Weapon Light Switch Assembly w/Picatinny Pressure Pad

Works great. Typical SureFire quality. Not much to say there.

I don't take credit for this (I think it was on BigTex Outdoors or something like that? Google it): The RM07 switch will work with the Cloud Defensive mount for the STREAMLIGHT pressure pad. You read that right. Cloud Defensive mounts are the bees knees, and they make them for both SF and SL. The SF one is only for the UE07 switch, which just has the pressure pad and is flat. The RM07 pressure pad (momentary + constant on) is rubberized and has a built-in rail interface, which isn't bad but the CD mount is waaaaaayyyy better. So, all you do is: Order the CD mount for the Streamlight HLX, then shave the rail grabbers off the bottom of the switch and make it flat. I used a sharp razor knife to get it close, then a belt sander to get it perfectly flat. Then your RM07 slides into the Streamlight HLX mount like a GLOVE. It's pretty awesome. Great setup.
