SIGfever, I have the Desantis mini-scabbard for the .45 Shield and it does not slide on the belt at all while being worn. I also like the tension screw, so I can loosen/tighten to the draw speed I want. Best of luck in finding what works for you.
Thank you for your service to our Country! I really like its small foot print and form factor. What size belt do you wear it with?
