I guess I dont know how optimistic and trusting you are regarding others with guns. I know everyone has to start from somewhere. I've seen a lot of new people that couldn't hit paper, and a lot of seasoned owners with bad habits, bad form etc.
Just because you bought a gun or have one in your hand, car, house doesn't make you by your word effective. Sure you can probably hit something depending on how many rounds are in your gun. I see people all the time drop the magazine thinking it's a safety. If you walk up to any person that doesn't shoot and ask them to show you or tell you how iron sights work, they won't know. People that don't know anything about guns simply don't know anything about guns. Whether they watch youtube or go to a class information is being passed on.
Yeah with time, trial and error is fine. If you practiced enough you could shoot with your toes and hit a target every time.
The purpose of training isn't to believe everything you hear but to learn things whether informative, or practical and implement or not. And if something makes sense to you, to do it. Rather than. Close yourself off and learn things through trial and error. Especially when that could mean your life.
Speaking of the isosceles stance. Thats fine for cops because they have a bullet proof vest. You probably don't wear a vest therefore you don't want to present a broad Target for someone shooting at you, and if someone rushes you in that stance you are going to fall straight back on your ass. So when you stand up with people and they are in that stance and you push them and they stumble they say"
what's another way or a better way to stand?" Yeah, you don't have to push everyone, some people can hear and see that on a youtube video and implement it, hell some people might find a way to use a head butt or front kick to deflect it and tell you or me "isosceles stance is fine, here's what I do" but trial and error , especially when the exchange of proven techniques, tips and feedback is just silly. Theres no one right way, like I said you could teach yourself to pull the trigger with your big toe, but there are more effective ways of shooting, becoming a more effective shooter, and learning or encountering them in more efficient ways than just trial and error or even a lonesome video. But you do have to practice and implement, whatever your doing. Just having a gun in a drawer for 5 years ain't shyt. You need to shoot, practice shooting.
And don't forget to take into account that people are fukked up, can't raise one shoulder or rotate their hip or spine, can't bend a knee, have arthritis, people scale back their firearms all the time. Having a hand cannon is cool at 30, maybe not at 96.
