How easy is it to disassemble the XM-L EDC? I was thinking I could get one in copper and take it apart to gold or nickel plate, then reassemble it. This would prevent it from tarnishing.
Nickel-plating copper should be a crime. If you're going to nickel-plate something, at least make the base metal something uninteresting to look at. Perhaps a bare aluminum light would be better if you really want to nickel-plate it.
