I have the serpa leg platform and routinely wear it out in the bushes and the range. I do tend to bang around my gun a bit, but its my beat around gun. I'm not to worried about scuffing it up a bit. The serpa rig is actually not to bad to wear once it is adjusted properly. I can get in and out of the truck with no issues. And running short distances have not caused me any problems.
One thing I like with my leg holsters is to wear it more forward than the centerline of my thigh. It helps keep the gun out of the way.
