He's an active duty SERE instructor in the Air Force. He is definitely one of my favorite gear reviewers due to the fact that he gets to test a lot of stuff in the field. :thumbsup:
If you aren't as worried about finding holster options, take a look at the Olight PL series lights as well. My PL-2 is brighter than my TLR-1 HL and the new ones have a magnetic charger to constantly keep them topped off.
