Dont buy, design flaw - Streamlight TLR-1 HL CR123A LED Rail-Mounted Tactical Flashlight

One day this will happen to you. The End cap that holds the batteries in is made of 2 pieces, 1 internal 1 external. The internal piece is not only the mount that holds it all together but also the mechanical switch for on and off and the battery spring housing. It is held on by very weak glue. It will fail eventually, its a terrible design that should not have made it to a store. I have a ton of streamlights, but this light should not be purchased.
