I carried my Shield 9 in a Desantis Apache for a couple of years as my BUG on duty. Been in numerous foot chases, fights, etc with it and it never moved. Hell my first foot chase wearing it I had to jump two fences and it never budged. Wore it over the top of my 5.11 ATAC boots. Hardly ever felt it was there. I picked it up for around $45 at Bass Pro, but I'm sure it's cheaper on Amazon now.
