I was so happy with the first one I bought that I bought a few more. The belt loop is not attached so you can place it anywhere on the belt without it getting in the way of the pants belt loop. A very good feature. There is a little difference in length within the size range, but it is very slight, maybe an inch. You can also adjust the length by loosening the screw at the end of the buckle and trimming the strap to your desired length.
