Personally I hate CR batteries. They're expensive and not so,etching I consider easy to find if I need them on the spot. I tonight see eotech has a AA weapon light so I co,e here and hit the search tab, seems like nobody has one. I'm hoping I missed it or nobody mentioned buying one and looking for reviews
While I too hate the CR batteries that thing looks way too long for a pistol. Now a rifle it would work for some. I also don't imagine there are any holsters yet to accommodate the light left on a pistol. I add that I haven't look either so if there is one then it's because I didn't bother looking.
