From what I am seeing you may have the holster set too low. While it's desirable for concealment, your belt is pulling the firearm too close to the body, and letting your hip push out the barrel. Move it up a hole or two and see if that helps. I know this will mess up the cant angle you want, but it might work for you.
If my suggestion doesn't work it's not the end of the world. Just practice with what you have in slow motion and get your muscle memory built up for the way you do it. I never wrap my thumb around the grip until the gun is almost out of the holster. My thumb is what moves my clothing out of the way, and for what I wear it works very well.
By the way, you need to decide which holster you want to wear and throw the other one in the holster box. The cant is different on each of them, and this will hinder muscle memory development.
