I dug around in past posts, but I couldn't find any kind of firm guidance on this subject. I have an XD-S Mod 2 3.3" in 9mm, and I'm hunting for a weapon light. The closest possibility that I can find is the Surefire XSC, but it specifically says that it fits the Hellcat. Has anyone tried this on an XD-S, or have any other recommendations that work properly?
