Thanks for the link AK. I definately see what you're talking about; it certainly has more of a defined holster, as opposed to a pocket. One ting that stands out to me is the lack of anything to prevent printing. I think I have to give a point to the 5.11 for the "foamish" lining of the outside and inside of the holster pocket. I think it helps cusion your body from the firearm and helps to break up any hard lines from the firearm that may show on the cover garmet. But of course, that all depends on what your cover garmet is.
I really thank you for bringing that info to the thread. Cowboy, OP, has posted questions on the 5.11, and now he has info AND options. Aint TFL great?
