Bought two of them
First a black one for my Masada. The switch wouldn't rotate very far. I figured out I needed to remove a blue Allen head screw that has keeping the switch from rotating. There was nothing in the manual about this. I so like the XVL2 that I bought a second tan one for my Glock 19X. It did not have the blue Allen screw so I'm guessing it was supposed to be removed at the factory. I purchased both from OpticsPlanet who are very good (in these crazy times) about either having stuff in stock or getting it quickly. Super pleased with both XVL2's.
