Practice is what it takes, and a lot of it.
Get the draw down so it is smooth and the speed will gradually come.

Trying to push for the speed while learning the draw will result in a lot of wasted time and ammunition.

Even at Gunsite the first emphasis is on getting the draw down to be smooth.
By the end of the week (and around 1000 rounds latter) the speed is usually pretty good.

You do NOT want double taps closer than about an inch.
You already shot the guy there once, make a NEW hole at a different spot.
You are more likely to hit something else important.
