That's not at all certain!  Your whole point is hinging on the fact that a gun is deadly at long range while a knife is not; therefore there is a huge incentive to NOT close with a knife-wielder, while there IS a reason to approach a gun-wielder (one who is only threatening you to get something out of you, and not shooting on sight) and then trying to grapple it away. 

You're simultaneously acknowledging that a knife is only effective at close range while a gun is not, and claiming that a person facing a gunman would be no more willing to try to grapple it away than when facing a knife-wielder, as opposed to simply running away.

Its true a gun is more deadly over a distance than a knife, but it is also more deadly close up than far away. Aiming a gun drunk is extremely difficult, and that is not really a secret.Someone willing to put a gun at point blank range probably wouldn't hesitate at the thought of something less intimidating.
