Several people made the old "swivel holster". Bianchi, and others. Like you said, it was to unsnap in the car, and was for a short waisted, long armed officer to get a better angle on the draw. It never really caught on in the south, as the leather snap leather stretched and the holster would flop around on the run. Haven't seen one of those in years, but can remember rookie officers buyin'em and swearin by'em. For about a month, and then it would "disappear" from his wardrobe. Still, it's a piece of L.E. history.
