I don't think you'll have any problems - it fits on pretty tight. Although it would probably loosen with time if you removed it repeatedly.Thanks for the great review! I've been considering getting a TK12. How substantial was the pocket clip? I'm looking for a TK12-ish tactical light w/ a decent strength pocket clip, as I'm in scrubs most of the time and carry IWB.
Anyone here with experience with extended carry? Please chime in ...
