I'm going to assume you didn't mean that to sound quite as cocky as it did.
On the off chance that you meant it how it sounded, the following applies: Situational awareness is key. If you let a bad guy get too close, you could easily be stabbed before you can draw and fire, and once that knife is going in and out of your body, you're screwed even if you do get a shot or shots off.
Don't get me wrong, I'm planning on getting a carry permit soon myself, but much like 4 wheel drive doesn't give you license to drive like an idiot in the snow, carrying a gun doesn't make you immune to attack. It gives you more options, sure, but nothing makes you invincible, and it's a very heavy responsibility. If your gun goes bang and somebody dies, it will change your life (and probably the lives of those around you) forever, even presuming you're found to have acted in self defense. It's not something to take lightly.
Please don't assume to know me or anything about my level of responsibility and awareness with a handgun and then proceed to scold me on actions I've never taken.
