Oh - clips. They generally suck. It ain't that hard to thread a good belt through loops/slots. All the clips I've tried either don't hold well or are just as much a bother to apply.
The IWB holster I've been using exclusively for the last ten years or so has been the El Paso Saddlery C-Force, and it has a single snap on loop. It uses a high quality snap, so it has never come undone on me while wearing it, and is no problem snapping on or off the belt. No need to thread the belt through the loops, although that's how I used to roll when I used Milt Sparks IWB holsters, and it was no big deal doing that, either.
