I like the dash myself then the pistol is visible pretty much 360. I've buy the cheap gray Serpa paddle holsters on Amazon for ~$25 and they work well. First I cut down the paddle to a rectangle then I sand it flat on my belt sander. I use velcro to attach them to the dash. I'm pretty anal on muzzle direction so I've actually changed out screws and used washers to make sure that the mount angle on the dash points the muzzle down in my cars direction. I need to snap a photo of it.
