Seek some professional training. Some training is boring and may be below your personal skill level. It’s ok to go thru the basics. Instilling safety habits early is paramount. I’m a certified pistol instructor, and you’d be amazed at how many safety mistakes I see during a class. Endless amounts of sweeping people with muzzles. Sweeping themselves. Loaded or unloaded, it’s frowned upon. You want to build a mindset that prevents you from ever sweeping anyone unless you intend to points gun at them. With training, you’ll feel a physical reaction to intentionally pointing a firearm at someone. You’ll find you keep your finger off the trigger or spray bottles and electric drill guns.
I hate teaching big classes. Which to me is anything over 5 people at a time. I like a hands on approach where we fire 1-3 rounds, approach the target and assess what they’re doing. Attempt to correct what is wrong and try again. Blue tape over the holes so we don’t get lost on the next set.
I agree most of the YouTube channels are full of crap. They may pay lip service to safety and training regiments, but it isn’t the primary focus. Their focus is to tell you to like and subscribe several times to their entertainment based channel.
