I my self have considered CC. And I came to the conclusion that I'm going to buy a hand gun as soon as a turn 21 and get a CC permit as quickly as possible. I live in downtown Atlanta and I know for a fact its not safe. I support your decision on getting a CC permit. Its a crazy crazy world out there, with all these school shootings and senseless killings I feel that it is imperative for sane law abiding citizens to carry some sort of self defense tool, whether it be spray or a gun.
After you reach your decision of getting a permit, a hard question will arise.
What type of gun to get, and at what caliber.
I dwelled upon this question for quite a while. I really like the classic look and reliability of revolvers, but the ones most feasible for carry are small snubbies with short barrels and small magazine sizes, which I don't like.
So I have chosen to get an automatic pistol. I have yet to come to come to a single pistol which is "ideal" for carry, but I have narrowed it down. I did some reading on the internet and it appears that Glocks and HK USP are the highest on reliability and durability and pretty much NEVER jam.
As far as caliber, from what I read 9mm is slightly weak for stopping force. .357, .40, .45, .380, are more potent calibers for power. Though in the end it comes down to your frame, and what caliber you can shoot accurately.
And keep practicing after you get your CC permit, practice drawing, cocking, and putting lead accurately on target at around 7 yards until it becomes instinctive and second nature. You have probably heard this a million times already but I'm gona say it once more Run if you can, the gun is the LAST resort. Only use it when the attacker gives you reason to believe he will inflict fatal harm to you and you genuinely believe your life is in danger.
I'm gonna end with a proverb:
"it should be comforting to carry a gun, but never comfortable."
