Some thoughts - you are looking at this entirely with a wrong focus.

1. Don't get into a physical altercation over property.
2. Don't get into a fist fight with someone when you are old
3. Don't get close to an opponent
4. Self-defense training doesn't mean you win a fight. Most decent SD training is to escape and not to attack.
5. Who gives a crap about a safety or retention holsters if you are foolish enough to get in close.

I know some folks are safety fans (I hate Glock, blah, blah, blah). Well, so close up, are you sure that you would take off the safety in the stress of the gun fight? Would you draw the gun before you closed and then take off the safety? Why assume that you know there is a safety and your opponent doesn't.

If you have retention holster, are you going to put in the 3000 dry fire draws and flipping off the safety to make it unconscious, if you are foolish enough to get that close.

The store clerk, good guy and brave, failed from the beginning of the incident.

The equipment discussion is really not the point.
