Most here seem to agree that a semiauto pistol with an empty chamber is a CCW liability.
It's what I like to refer to as the "gun as talisman" form of self-deception, that is, "I have this item, so I 'feel' protected".
Anybody who carries a weapon or other "item" such as a blade, needs to seriously consider the issue of worst-case deployment.
Awareness and avoidance will go a long way toward keeping us out of trouble, but if we ever unavoidably "get down in it", it'll likely be sudden and unavoidable.
Consider being assaulted in an elevator or other situation where you can't escape and can't move much; are you going to rack that slide, or thumb that pocket folder blade stud (or blade hole) or flip that Balisong?
No.
You'll likely be fumble-fingered at best, and you will very likely first need some sort of "empty hand skills" to just get sufficient freedom to even reach your "primary self-defense item", so it better be accessible and require nothing by way of intermediate steps to make it useable!
Preaching to the choir, I know.
Best.
