Glocks are popular for a reason. As far as buying one, you should see if you can find a range that will rent them to you first. To my experience, different people "click" with different guns, and so if you're going to spend that much money on something, it's worth trying it out first. I'd also highly recommend taking a basic pistol course of some kind, whereby someone can walk you through basic operation and safety and maybe teach you some marksmanship too. Beyond that, it's a perishable skill, so if you do want it for self-defense, make sure you practice and practice often! One last thing: I for one wouldn't keep one in the glove box when I'm not in the car. It's just asking to get it stolen. On a related note, never put a bumper sticker on your car that suggests you're into shooting--that is a great big sign that says "break into this car."
