The Balckhawk Serpa paddle holsters are very secure OWB by design...they are almost difficult to get off. They offer adjustable cant as well.....but in my opinion they dont hold the gun close as you would like, by your statement. Personally I like the way it holds the gun because it gives you a bit easier time when reaching for the grip since it's not tight against the body. That being said, I just got mine for my J frame and still getting used to it. My first impression is quite good.
Never waste time deciding between two guns....buy both of them.
