In a self-defense shooting, if you have a failure you want to put the gun back into working order as quickly as possible. I am not going to bet that a round of ammunition which has already let me down once might come through for me on the second try.
My training was to TAP hard on the bottom of the magazine to make sure it is properly seated, RACK the slide smartly to the rear in an attempt to clear the malfunction (ammo in this case), and READY to assess threats (it used to be TAP, RACK, BANG which I liked the sound of better. I'm sure some lawyer somewhere made them change it).
Another thing to consider is that in the heat & stress of battle you might not immediately realize what the problem is other than the gun is not firing. It may be a feed malfunction such as a stove piped casing instead of a bad round of ammo. The malfunction clearance will fix either problem.
