Nobody notices
the black clips **unless they already know what they are**. From all angles you can only see one at a time anyway. In almost all environments, people just don't expect you to be carrying a pistol, so they just don't see it.
There was a discussion about this a while back here, to wit: what do you tell people who ask what those clips or snaps are? Most people, as I said above, don't really think about it anyway, but only once have I ever been asked, by a nurse while she was assisting me in a procedure which required her to stand directly behind me for about 30 minutes. I said that the belt was a dress belt designed to be usable as a gunbelt, and the clips are for when I want to attach a holster to it. Seeing no gun, she naturally took those (true) words to mean that I wasn't carrying at the time, just wearing my gunbelt.
