What do you mena when you say concealed carry? I imagine permits and I'm not going to get one of those.
I cannot say for sure whether or not permits are what you need to be worried about. The registration of firearms is probably what you should be most worried about. But all in all the choice is up to you; most training programs are geared toward CCW licensing or things to that effect.
If you want training on the cheap, I suggest checking out videos from this YouTube channel:
Scroll down and take a look at the tactical training playlists and get yourself a green gas blowback airsoft. From there you can pretty much practice all you need to practice at home with a good degree of realism at a tiny fraction of the cost of going to a local range.
No one will even have to know you have a firearm yet you will still have the means of learning how to use it and practicing that process.
