It's a state/local issue....depends on your jurisdiction.

It is correct in FL that printing, and now even displaying your firearm in public- so long as it is not done in a threatening manner- is legal.

So if someone says "Can I see your gun" in a parking lot, it's perfectly legal to show it to them...
I have conducted several firearms sales (including handguns) FTF here in FL in the local Wal-Mart parking lot. Weapon out on the hood/truck, etc. being inspected. I do it in a less traveled area of the parking lot, but certainly visible if someone happens by.

That said, it's commonplace when you first start carrying to think that everyone's watching you...and can see your weapon. Not the case...
