First off, Congrats on your first sidearm and welcome to the official world of OC.
Read the laws, know the laws, and when someone you encounter starts telling you that OC is illegal, that's your chance to shine! When others ask you about your weapon or why you carry or try to tell you that it's illegal that's your chance to help educate your fellow Kentuckians as to their Rights to open carry in the Commonwealth.
Now as for your choice of OC holster. I myself have one of those and while it is one of the most comfortable OC rigs I own, I rarely use it often. The reason being that for some reason it seems to needlessly alarm "the sheep". *LOL* While I don't really care what others might think of me personally for carrying or what I may be carrying, I do also understand that making "waves" needlessly can act against the OC'er in general.
While drop thigh rigs are fully and completely legal, they seem to attracted unneeded attention fro LEO for some reason, I guess it because they are general thought of as "military" holsters due to movies and TV shows casting them only in that light for the sheep.
Please don;t get me worng, I'm not trying to say not to get one of carry with it, I've just warning you of what you might encounter when carrying with one. Me personally, I love that OC configuration.
