Hey guys I have several holster that i carry my Glocks in. Every one of them will "walk" backwards to the rear, and out of were I need or want them. Besides putting on a extra belt loop on my jeans is there any other quick fix for this??

I've thought about puting a string on the front belt loop and then on the hoster to try and keep it in place.

any other ideas??? and I do have a "Good" belt ( Looper leather with kydex)

thanks
