When you draw from concealment, an experienced shooter needs only get their grip and an eye picture -- point gun at target and fire. You only need to train muscle memory to get into a firing position, which is also what you are regularly training every time you live fire or dry fire.

If you don't have a round chambered, you need to draw, rack and release the slide, hope a round is properly chambered (in a panicked situation you might not rack the slide properly), then get into a firing position. This is a much more complex movement and evaluation of state. You are pulling the gun up, manipulating it with two hands, then moving it forward and finding your grip. In an emergency, that time loss and complexity of motion is considerably more difficult to train.

Even experienced shooters will draw from a holster and immediately present their gun and try to fire, and then realize they don't have a round chambered, have to bring the gun back to rack the slide, and then present the gun again.

You conceal carry because you want to be prepared at an emergency to deal with an imminent threat. Adding complex manipulations to that erodes your ability to do that, and any modern pistol should not fire unless you pull the trigger. They should be safe from drops, shakes, or manipulations.

If your threat isn't "I need to have a firearm ready asap", then you should consider not conceal carrying, in which case you may want your pistol unloaded or unchambered.

I’m a panicked position maybe you should not fire a gun.

If you cannot even chamber a round who’s to say you can hit what you want to hit?
