A lot of good advice here. At 19 I know you feel you are fully grown up, but whether you want to beleive me or not, you still have a good way to go. Don't be in such a rush to get into concealed carry, which is something you are two birthdays away from even under the best of circumstances.
I suggest that you start with a simple rifle or shotgun after getting some basic training regarding firearms and gun safety. You might find that shooting is not something you particularly enjoy, or might find that it is a very satisfying and fun experience. Starting with a 22 caliber rifle at a good range is likely to get you started in the most positive way. When you decide that you really want a pistol, you will find that a revolver is simpler, more reliable less likely to be problematic or unsafe for you. I have helped a few people get started in shooting handguns, and found that a 22 caliber revolver is the ideal gun.
Before picking your carry gun, by the way, you can try various guns at commerical gun ranges. What you think of as a great gun might turn out to be something uncomfortable for you, or something you have difficult shooting well. Trying various guns by range renting is a lot quicker and less expensive way to find out the right gun for you.
