I've got one. Bought the leather one, then bought the nylon one. The leather one was just too dressy, was too noticeable. Feels like you are carrying a hugely obvious when you wear it the first few times, BUT, it really is not that noticeable to the casual observer. It has it's place in the various OPTIONS for concealed carry. While I agree with some that a good IWB or high riding OWB are the best, (I normally carry in a N82 IWB) I would not be so crass as to laugh at an American :nono: who has decided to try to do his part and carry legally and responsibly. Far be it from me to denigrate someone else's good intentions.
I have not used mine often, but I have used it in several large groups of people, and only had two people ask about it, and that was to ask how I liked it since they had seen it in American Rifleman magazine.
The leather one actually fits in very well with Dress Clothes, if you often have to wear those. The nylon one blends in pretty well with jeans, shorts, etc. Mine is made for an LC9s, which is not a very large pistol. A full size gun would probably require one WAY too large for me. My 1911, for example, would probably look like a suitcase, lol.
Bottom line, you decide what YOU think works for you, regardless of what self proclaimed experts may say.
