Leaving a gun in your car is irresponsible; that's a very common way for them to get stolen. The modern thinking on this is that you should carry it on your person at all times or leave it at home (e.g. if you're going to a place you can't carry it). Additionally, frequent "administrative handling" of your gun (like unholstering it in your car and re-holstering it when you get out) needlessly increases your chances of a negligent discharge, so moving it off of your body when you get in your car is also discouraged. Of course this doesn't mean that everyone knows/thinks this way (and many don't), but from my discussions with other firearm advocates, this is the modern school of thought. So—to answer your question—a Glock 19, and yes, as it's on me already ;-)
