I've been looking at the Olight lights as they seem to be a good value. . the Valkyrie Pro and PL2 as welll as the mini. What do you all think? Is the rechargeable battery worth it? I was planning on using it on a CZ P09 but might use it on my AR. Would the pressure switch work well for that? or should I look at something like the Streamlight TRL-7 or 9? Is there a durability difference? I've got a lot of questions as I'm new to the flashlight thing. Any advise would be immensely appreciated.
