I remember when I first started having these same concerns and would spend ALL day at work considering things just like this. This is an important part of becoming a CCW holder. You'll notice that for a while after this class, you'll come across all kinds of new scenarios to consider.

One that I particularly remember is someone on another site asking about carrying in a movie theater. They were worried that they would print and a cop would see them. So you have to ask yourself, if your biggest concern is that an officer will spot your piece, and not if you'll have to use it or not, do you need to be carrying at all?

When you first start carrying, it will feel like you're carrying a flashing light and siren in your belt that everyone is staring at, but no one notices at all. After about a week you stop worrying if you are printing, but you will pretty much ALWAYS be mindful of your clothes and that they are not pulled up to expose your gun. I recommend carrying around your home for a while to get a feel for it.
