Mile High Tactical Solutions, it's employees', adjunct instructors etc. all support, enforce and practice the World recognized four (4) basic Firearms Safety Rules.  Although the four (4) rules differ slightly from country to country and language to language they are pretty much the same world wide.....

 Treat all guns as if they are ALWAYS loaded!

 NEVER let your muzzle point at anything you are not willing to destroy!

 KEEP your finger off of the trigger, and out of the trigger guard until your sights are clear and you are ready to fire!

 ALWAYS be sure of your target and beyond!
