Most of these techniques are taught at Front Sight and that is the safest way to learn them.
All drills set forth in this article should be practiced numerous times “dry” with an unloaded and cleared firearm before “going hot” and conducting the exercises with live ammunition.Conduct your live-fire practice with safety in mind at all times: Be mindful of the muzzle–it should always be pointed in a safe direction (and that includes not pointing it at any part of your body); keep your finger off the trigger until the gun is pointed at your target; and in drills that include one-handed shooting, be sure you keep your nonfiring arm behind the gun.
