I sent you a private message with more info.
If you go through with a gun purchase, you need to lear how to use it. There are lot's of videos out there.
The NRA has a video called "Personal Firearm Defense Series" great training that you can learn at home.
Even cheaper is go to YouTube and search for "Todd Jarret" he has a video on how to properly grip a pistol.
Experience is a very bad teacher because it first gives you the test and then teaches you the lesson.
