As stated above, using a firearm in self defense means shooting until the threat has ended (i.e. is no longer capable of harming you). Unless you get lucky and tag something that instantly incapacitates (a direct hit to the brain), chances are that even a mortally wounded person will still be able to fight for up to 2-3 minutes, give or take, before blood loss renders them unconscious and therefore unable to fight back. This is further complicated that pistols and other such small caliber, lower velocity sidearms do not have enough "oomph" to get the job done like a rifle (much faster projectile) or shotgun (heavier/numerous projectile) would. Hence why a mag dump into the aggressor is warranted.
Note: The subject of "killing power" is hotly debated among gun people. i would recommend taking a detailed look at that particular subject from good sources to get a better idea of what I am rambling about.
Correct me if i'm wrong. But that problem of the person still being able to fight after being shot wouldnt be solved with more stopping power, like using a revolver?
I remember my dad always telling me that a 9mm would kill but you wouldnt know it while a revolver .38 would put you on the ground death or not
There a couple of misconceptions here. First, a revolver is just a pistol with a feeding mechanism in the form of the cylinder rather than an magazine. Second is the Knockdown Power Myth. If I am remembering correctly, .38 is only a bit bigger than a 9mm round. It still lacks the mass and/or velocity to start getting into the nastier pressure cavities, both primary and secondary, seen with wounding caused by higher powered/faster traveling rifle rounds (which can be the same size or smaller than pistol loads, such as .223/5.56 rounds used in the AR-15) or the devastation that can be caused by more weighty shotgun loads (massive projectile in the case of a slug, or through quantity of decently massed projectiles as per buckshot) which can cause instant incapacitation. From what I have read (and I am not an expert), handguns are largely similar in terms of terminal ballistics until you are getting into the hand cannon ranges (.454 Casul or .500 Magnum). This is a very extensive topic. A couple of good starting points can be found here though:

A thanks dude. Will read to learn something new
