Anyone having trouble with the firebutton unscrewing? My friend picked up a clone, and the firebutton was unscrewing when you would lock it/unlock it. It eventually got to where the inner screw fell out and lit his pocket on fire. I wrapped some Kanthol around the base of the screw and it seems to be holding it in place, wrapped it tight to keep it under the button. But I think some T-Tape would be a better solution, but none on hand. Any ideas?
