The claw is a piece that attaches to the holster below the trigger guard and extends up even with the belt clip, about a half inch from the holster shell. When you tighten your belt, that claw is pulled in tight and causes the grip to pull in tighter. I'm seeing it mainly with IWB set up for appendix carry on around to 4 o'clock. I should probably learn how to post pictures some day.
I think I'm going to get a 10 degree cant and give it a try.
