Muzzle Discipline or controlling the direction of the firearm muzzle goes hand in hand with the Trigger finger placement. If we are thinking where is the muzzle pointed and is it safe, if the firearm discharged then we have avoided any injury to any one else even if we had a negligent discharge of the firearm. We need to plan for messing this situation up because eventually we will. We can instill good habit patterns in ourselves and mitigate 99% but at some point we could forget to check and assume it is unloaded. We should prepare ourselves in our training for Muzzle Discipline and to know where the muzzle is pointing at all times. Paul Howe of Black Hawk Down fame says it this way. Muzzle direction is situational and needs to be thought about. If you are in a helicopter pointing it up might not be so smart. If you are in a boat pointing down might not be so smart. If you are in a crowded urban area pointing up might not be so smart . On an urban gun range keeping the muzzle inline with the Burm seems like a good idea since we the shooter are responsible for every bullet. We need to think where is that bullet going to wind up and this should be at the forefront of our thoughts before we decide to place our finger on the trigger.
