Practice. Draw your gun out repeatedly at home, slow fast, medium speed, whatever. Get used to holding your gun properly in a good grip. Make sure you know where all your fingers go. Memorize the texture of the grip on each finger. Slow down your draws to see where your hands might be gripping the gun wrong, and improve. Learn the movement of your slide when the gun is fired. Make note of your grip when you fire the gun, eject magazines, or pull back the slide. Squeeze the trigger instead of slapping it as fast as you can. Find a holster and gun that feels right to you. IMO, Glocks feel like crap and have nasty triggers, but if it feels right to you, go for it.
