Multiple attackers like this is one reason I don’t favor single stack guns although I do occasionally carry one. I like lots of bullets. If your going to hide behind a wall of lead, you want that wall to be pretty substantial. 6-7 rounds just might not be enough to hide behind. YMMV.
One has to be lucky in the order to begin with, then be able to make the shots that need to be made, and the most important criteria, confidence to make them. Confidence in your ability to make hits on multiples quickly doesn't come from static line shooting on a range. Confidence comes from prior training on multiples, Fof with multiples in various scenarios, and the competition circuit.
When one has the confidence in their ability to make rapid shots on multiple threats, it changes the nature of the mindset in the defender to go offensive at the first opportunity. Most others will hesitate to act, for fear of missing shots and being taken out.
In one of the courses at Volusia, I had people try and thread the needle on threat barely visible between two innocents. They could take their time to make the shot [ which wouldn't be the case in a real scenario. Out of 20 people, 3-4 made the shot without hitting an innocent. Basics of handhold, trigger control and sight alignment just hadn't been mastered yet, after years of shooting on a static range.
Then asked if I could make the shot when everyone had tried, I drew and fired on the threat in real time and made the hit. Having been given all the time they needed to make the shot and seeing only 20% could make it with no time constraints told me in scenarios like this [ shooting in and around innocents ] most everyone is NOT going to attempt to make the shots necessary to affect a positive solution.
It was if I was seeing another course just covering basics and making precision shots all day on different threats/scenarios as viable. Never pursued that course outline, but I bet it would be an eye opener for many people.
In my humble opinion, there's few here who would use an offensive posture/tact to affect a resolution that leaves them alive. In my opinion, once again, most people deep down inside know they wouldn't fair well because they don't have the skills to thread needles or make precision shots on the fly. And we're not talking 20 yrds out, or ever 10 yrds out, but inside a gun store where the longest shot might be 21 feet.
If you hesitate to act on your own behalf being threatened with imminent grave bodily harm or death because you lack the confidence in your ability to make rapid hits on multiples inside 7 yrds, there's a way to resolve that hesitation,
Get the training.
