Yea this is true, good points and something to think about, especially the final point.You'll see this phrase a lot in here "concealed means concealed". If you're going to get your CCW and go through the trouble of carrying concealed, then you want your gun to be concealed as much as possible. You and I may not be bothered by someone who is printing, but do we really know if they're a law-abiding citizen with a CCW? They know but we might not know. And we know that we're law-abiding citizens who have gone through background checks and jumped various hoops to get our CCW, but other people in the store, restaurant, or wherever, they don't know that because they don't know us.
IMO, it's better to be totally concealed so I don't raise any eyebrows. Today's society is pretty screwed up and I'd guess that a lot of people could be on edge when out and about. Last thing I need when out shopping is to be printing and having some citizen who doesn't know me run to the store manager or call an officer. Sure, I'm legal and all, but I really don't want to be called out and have the police there causing a scene with yours truly. Much better to be in stealth mode and go undetected, so I can go about my business without interruption.
Plus, if there is someone in that store or restaurant or wherever, who has criminal intentions, he may not be planning on hurting anyone. But, if he sees that I'm carrying, I pose a huge threat to his plans and his life so guess who his #1 target to take out of play would be?
