RE: Car...depends.
Locally, the gun will be on my hip, in my pants pocket or in a SIG Concealed Carry Jacket pocket in the winter, along with extra ammo, so same same.
If I'm on the road, I typically have two guns...one in a crossdraw/driving holster and the "car gun" in a SafePacker. The car gun will be a little beefier or have lots more ammo, depending on my mood. Lately I've been traveling with the Carry 9 in a Blocker crossdraw and/or the jacket holster, an extra magazine for the Para in my pocket and a heavier revolver in the car. The revolver is usually a 3-inch .44 Magnum loaded with ammo that would penetrate a train locomotive end-to-end, my thinking being that while I trust my 9mm CorBon for antipersonnel situations, I'd like some back-up in the car that will seriously penetrate. I carry an extra speedloader of the penetrators and a second speedloader of Black Hills 240-gr JHP. If I get down to the 240-grainers, I'm in deep dookey...
