I don't usually unholster, but I've found that a paddle style holster fits over the lip of the driver's side door pocket and holds the paddle holster quite well. If so inclined, I would enter the vehicle, unholster and put the gun in the paddle holster. Works better for me as I'm left handed. Using a right handed paddle holster lets me keep the gun by my left hand while driving. Before I get out, I simply remove the gun from the paddle holster and put it back in the belt holster.
