Seatbelts and coats tend to get in the way, especially in the winter.
I have gone to a cross draw holster for when I am traveling. I position the holster where the seat belts do not interfere. I always clear my shirt or coat, too, so I have the piece concealed, but have random access with my right hand. Comfortable, fast, and discreet both in the car and when I go walk about. I carry it between 0900 and 1000. Try it. You might like it.
