Bullseye, that is so Not True.
In response to the original post... Here's the deal... If you are not sure of yourself,
Don't try it!
Most of the usual ccw permit holders do not train for, or have training in handgun retention and disarming techniques. I train regularly on handgun disarming and weapon retention, but I'm also a former LEO trainer for those techniques using the Jim Lindell method of weapon retention and disarming techniques.
It is not particularly difficult to disarm an assailant when they are at contact range with a gun pressed against your body. Even at a distance of 2 or 3 feet away. However, it is nothing to play around with. I can not stress that point enough.
You need to follow proven techniques to trap, control and or leverage their weapon to gain control of it. You need to understand how leverage works in your mind, and you need to practice these techniques until it is second nature and built into your muscle memory. If you are not well skilled at it, you're likely to end up making a fatal mistake.
Making a half assed attempt at it while trying to simultaneously draw your own gun is a move which would likely get you shot or killed. You need to commit to the disarm and use both hands. Do not try to perform two totally different skill sets or actions at the same time.
There are also big differences between redirecting the muzzle of the assailants weapon while drawing your own and firing... and disarming the assailant. You have to know which technique you are going to perform and which technique is going to be the appropriate response. You can not do that without formal training and a lot of practice.
Then there's probably the most important component of all. You have to have the guts to act! Again, a half assed attempt and any hesitation based on your very real and acute level of fear is what will get you killed.
I've said before, a genuine, combat, aggressive mindset does have a tangible effect on the outcome. If you are not absolutely convinced in your heart, your mind, and your soul that you will be the victor, you will be the winner, you will survive any and all comers, you are likely to come up short. Another thing is that you have a deep understanding that there are no guarantees in life. Even with the combat, survivor mindset, years of training, professional instruction, you have to accept the fact, that you may still lose the fight.
It's understanding that, and being willing to fight on to overcome your fear is what's gonna determine the outcome.
