I'm going to go against the grain here--most people taking CCW are probably self-defense concerned people who are likely--but not always--not going to be serious gun enthusiasts like those of you reading this. CCW requirements vary from state to state--some you just fill out a piece of paper and your done--others require an intensive multi-day course filled with written and practical content.
My CCW class was taught by police department officers--so they naturally leaned heavily into legal ramifications. I'm glad they did; in my experience the majority of "casual self defense carriers" honestly don't have a clue what kind of legal trouble they can easily get into.
Incidentally, my class was a big one--some 50 or so people as I recall. Everyone had either a 22lr or 9mm because they thought that would be the easiest way to pass the shooting qualification test. I brought along my 45 XD. Reading the comment above about the hot brass going down the shirt brought back memories of my test--a spent hot case from my XD went down the front of my shirt--and into the front of my gym shorts. I secured and put the gun down on the shooting table and started a vigorous dance to retrieve the case. For the rest of the class the officers present always cracked a smile or chuckled whenever passing by me--I made a big impression I guess.
