I’m small and light (105 pounds), so I might very well run into an attacker twice my size (210 pounds) or even bigger. If I have to defend, my punch may not knock him out or hurt him enough to get away quickly. It could, but worst case scenario it may not. So, maybe I hit him, stun him for a moment, get the weapon, but he is quick enough to get a hand on it (he will be fighting for his life, too, he doesn’t know if I will shoot him with the gun once I got it, so he will try to get it back).
Another thing that could happen is that you are able to make some distance, but the gun jams, or you might need to rechamber it before it is ready to fire again, so maybe he charges you as you are rechambering the gun and before you are able to fire he is on top of you, grabbing it.
