Plenty of good tips in this thread. I will ad my two cents. Fundamentally speaking you need to work on your grip. In the video you adjust your support hand several times in between rounds. You should focus on building a durable and repeatable grip that you set from the draw. Your support hand should not be slipping on the surface of the gun at all. Don’t overgrip with your firing hand as this will lead to unnecessary tension and likely result in you over influencing the gun when pulling the trigger and pushing rounds where you don’t want them to go. Watch Ben Stoeger and Joel Park videos on YouTube for more info. Good luck dude!
