GEEZ Nemo!! What are you doing to that D10 I sold you!!:mecry:If this keeps up I may have to demand you send it back!!
As a temporary solution you can use a split ring in one of the holes on the tail and run some paracord thru it then attach a carabiner clip to the other end. Clip the Carabiner to a belt loop and you can hang the lite down into your pocket. If you get the length right and use the correct belt loop the light will tuck right into the outside edge of the pocket and yu will barely know it is there. When needed just pull it out via the paracord and quick detach the carabiner clip or leave it clipped for added security if you are Out In the Field working. The split wring will eventually start to take some of the HA finish off on the edges of the hole . Paracord with the "guts" removed will fit thru the hole with a bit of effort, I find using a piece of the guts of the paracord tied to the end of the gutted paracord allows one to pull it thru the small hole .
I have gone thru many of the "ideas" like what you have tried. I have found superglue to be pretty much useless for most things especially something EDC. Something like a clip takes alot of abuse on a daily basis. If it isnt screwed or welded on or something its gonna come off. Even Epoxy wouldnt hold up . Smooth surfaces with no joints give the epoxy/superglue nothing to "hold onto" and the glue itself can be "brittle"
I have actually found this method quite functional for EDC to the point of not needing a clip anymore.
