I've always felt firearm training vids are kinda... weird.
It's one thing to watch like Tim Kennedy or Costa video where it's like 10 minutes of them going "here's a couple options to try to maybe shoot your pistol better, I'm going to demonstrate them" vs that dude that is overly specific via video for how to shoot.
Granted, I might be jaded given I learned to shoot from my dad who was a vet and have multiple friends that served that I go shooting with the hound me on how to properly shoot and shit.
