I'll share what several big name/reputable shooting schools teach, as well as what I've found to the most effective.
Note: This particular draw method is akward at first... like VERY akward. But it is actually faster and more consistent than most.
Carry at 3 or 9 depending on R or L handed. This maximizes draw speed while still offering good concealment. For those of us who OC, it's ideal. It's recommended that you ride the gun vertically, with no cant... technically you loose a bit of concealment (if concealing of course), but in my experience, nothing significant.
Steps of the draw.
1. Grab you gun with a combat grip (don't pull it out, then shif it in your hand... draw it with a full normal shooting grip on the gun... like Whiterabbit said, this is CRITICAL) - while you're grabbing your gun, place your support side hand just below your strong side pec open handed. These two things should be done simultaneously. If you go for you gun, even in practice, the support hand goes to the chest. This keeps your hand out of the way in close contact shooting as well as preps you for step 4.
2. Draw the gun from the hoster upwards untill it clears the holster... DO NOT tilt the gun towards the target yet and DO keep your finger off the trigger.
3. Rotate your elbow down and slightly tilt your wrist till the gun rides uncomfortably high (almost in your armpit) and is pointed at your target (the reason for the step is to give you the ability to do point-blank shooting while keeping control of the gun and prepare you for "presentation" of the gun). You might have to tilt the gun slightly out to clear your pit.
4. Start pushing the gun hand forward, placing the finger on the trigger (taking manual safety off if any) and you'll find that your support hand is already (remember, it's just under your pec) conveniently in place to just slide out right into place for a proper grip.
5. Bring the gun up to eye level while keeping a proper stance. For beginners to intermediate shooters... DO NOT hunch your shoulders or crouch your head... this hurts consistency and accuracy. Think "english gentleman" posture.
Ideally the moment the gun comes up to eye level, the sights will be aligned and the gun will "go off" as you'll have been building pressure on the trigger all the way up... but this takes some time to master. Untill then, present, then work on trigger control.
If you need clarification, lemme know.. I'll see what I can do about pics for the steps.
