I'd say it depends on how close you are to the person.
Imagine. If someone is standing approx. arms length and holding a gun to your face, they're probably looking right down the barrel of the gun. Which means they're not watching your hands. If you have matial arts training, then you'll be able to move quickly, and thus could most likely have the gun knocked away before they even realized you were going to attack. Especially if they don't know you, and are relying on you being intimidated by the gun in your face.
However, if they're a few steps back, and/or aiming the gun at your chest/stomach, I'd have less confidence in such an attempt being successful.
And, if they're farther back, it would depend more on the type of gun they had, and how close you were to cover.
Either way, I'd sure as hell try, cause I'm not about to let some prick with a gun scare me. Because if someone can scare you like that, then they have power over you, and that's something I just wouldn't allow, no matter what the odds. If someone held a gun at me and told me to give them something, I'd tell them to stick that gun up their *** and come take it. Then I'd either get shot, or do my best the get the gun away from them. If I got shot the worst that could happen is that I would die. And I'm ready for that, so I'm not worried.
If you choose not to decide, you still have made a choice.
