Short answer: Yes.
I saw this posted on Facebook somewhere. The answer is “yes”.
Let’s put it another way: why would you NOT want a round in the chamber? For many, it’s because they are afraid. They are new to carrying a gun on their person, and they are afraid of what might happen. That the gun could “go off”. Well, modern handguns only “go off” in news stories and movies. Modern handguns are drop-safe, meaning you can drop them on the hard ground and they won’t go off from the impact. Guns don’t just magically fire; usually when they “go off” it’s because someone violated the rules. If the gun is securely in your holster and you aren’t fingering and fiddling with it, you have nothing to worry about.
So the fear is understandable (I went through it myself), but you must realize there is nothing to worry about, so long as you follow the rules. And a key rule is: holster it and stop fiddling with it.
I’ll put it yet another way. Do you know how fast an attack unfolds? Average gunfight lasts about 3 seconds. And given we’re the good guys, we only get to react thus we are behind the curve from the start. How much time does it take to rack one into the chamber? Maybe just a second, but if if you’ve got 3 seconds total to work with, that’s 1/3 of your time lost and you are that much further behind the curve; and that’s provided you don’t fumble. That’s unacceptable when every fraction of a second matters.
I’ve seen it over the years with some students that come to class with no round in the chamber. We have them perform some simple drills under modest but friendly pressure, and even giving them every advantage we can (e.g. round in the chamber, start from a ready position, fully mentally prepared). They often fail to take care of business within 3 seconds. So how can they be expected under extreme life-threatening pressure with far less advantage and head-start to be able to do what needs to be done? I had one student that actually had some conviction about no round in the chamber and racking on the draw. He held up modestly during class, but as the pressure of class increased, his skills decreased and I watched him fumble and fail numerous times. By the end of class, he was begrudgingly convinced that it was an unwise technique.
Yes, there are examples of people that can perform things like this wicked fast with fancy tricks. Great for YouTube videos, but just not a solid life safety technique.
In the end, I suppose you’re welcome to carry how you want. I would say if you don’t keep one in the chamber out of fear, I would recommend doing whatever it takes to overcome your fear, because when the flag flies, that fear is going to hold you back and slow you down far more than the lack of a round in the chamber (seek more professional training to become more comfortable and competent with your pistol). If you carry this way for other reasons, I would say to put your choice to the test. Take some Force-on-Force classes with Simunitions and try your technique out and see how it holds up under pressure. If you can make it work for you, more power to you. The key is ensuring you can have a technique set that truly works and covers the vast majority of cases. For most, a round in the chamber will serve them better.
