I�m not talking about what is behind the target. My goal is to make a shooter unable or unwilling to fire his weapon at me; that is my only goal. In a shootout you may not want to wait around for someone to bleed out while they have a gun in their hand shooting at you.
High velocity small rounds like a 9mm or a .223 can punch holes though a shooter without him knowing he has been hit.
Unless you are a pretty good point instinct shooter I doubt you will have �shot placement� on your side if it�s dark and you don�t have time to get a sight picture. The way you practice will determine how you will react in a shooting. At least that is what happened to me.
The caliber wars will go on forever, but some folks that are just getting started want information for choosing a weapon; and have no experience to draw from.
From what I experienced and saw firsthand responding to shootings; I don�t own any 9�s. To me a 9mm is a range round; not a personal defense round. However� as has been said many times�. A 9mm in your hand beats a .45 at home. Your weapon has to be comfortable to carry and you have to be able to operate it accurately and properly.
Application Driven.
