Well, I dropped the ride height 1/2" yesterday, and spent 10 hour dropping and logging trees for fire wood. It appears that the higher waistband of the jeans was the problem. My pants walked a about 1/4 of they used to. My bony hip must be forcing the holster around as I move.

I will make another J-clip with an extra hole in it so I don't have to move the T-nut in the leather backing (the other clip was already in the upper hole, so all I needed to do was move it to the next one.

Thank you all for you suggestions and help!
