I drive a two door full size pickup so.....
The side pouch on the door holds a G23 in a cheap uncle mikes holster. It is wedged in there so no issue of it moving around. I always carry on the body. Being a left handed handguner I find that I can draw my gun fine when seat belted. I can reach the G23 just as fast.
I also have a redneck rack for a shotgun. I love VT
