Wouldn't it be magazines or slings, Jorg?
I've found there are two types of clips. Those that are a {self moderated} to put on, but sit securely, and those that are easy to get on, but I'm afraid will fall off. I think if you're looking for a tuckable, clips are the way to go, but I've learned to appreciate the straps. FWIW, I have changed to OWB, which slides even easier, so I've gone to the straps.
