Wow, I had no idea my thread about buying an LC9s would morph into a back-and-forth about tactical pistol, but in a way I'm glad it did. I stand behind my own first recommendations, but I wouldn't try to force anyone to do things.
To my mind, you gain very little and have a big chance to lose a lot more by not carrying your modern "carry" pistol with a round in the chamber. I don't see what you really gain, and the chances you will be able to rack the round during an emergency being iffy aren't a matter of conjecture, they're a matter of study.
I think you can be reasonably sure of one thing: the Bad Guy isn't going to have to rack his slide to chamber a round. He's going be shooting at you, or pointing his chambered gun at you, or waving a knife at you, or someone else in your very close vicinity, in all likelihood. Places where you might feel danger or not sense danger intuitively are good sometimes, but not always. And nothing really ever works the way you imagine it will where human beings are involved. Einstein could imagine his way to Relativistic theory but people are not as easily derived.
Maybe the people in this thread who want to carry their guns that way will reconsider in the fullness of time. It's their option to do what they feel is best. These situations are decided in seconds and fractions of a second in many cases. Personally I wouldn't do it, but to each their own.
Regardless of what you think right now, honestly the best thing to do is get more training and spend more time shooting and handling whatever gun you choose to carry, so that you are the best - and safest - at using it that you can possibly be. Good luck and best wishes.
