Only an idiot carries with an empty chamber, and the PF-9 is DAO, so there's no difference prep-wise between it and a revolver...Just pull it out and go to work. I prefer the flatter and more easily concealed PF-9...BTW, if you have to use it, it will be confiscated, and if and/or when it's returned, you aren't likely to be happy with the condition it's in...I'd rather have that happen to a less expensive gun, all other things being equal.
