Being able to hit what you shoot at - That’s what it’s all about.
The fact that you’ve chosen to carry a firearm means you want to be prepared to protect yourself. Obviously. And good for you. However, simply having the gun isn’t enough. You need to, among other things, be ready and prepared to HIT what you are shooting at. Otherwise the resulting use of your firearm may create more problems than it solves.
Unfortunately, and to be blunt, most concealed carriers are not skilled enough to hit what they shoot at. I know I sound pessimistic, but I have seen it for decades; Shooters who do not prepare for the realities of when, where and how real world situations occur.
