What is the proper reload procedure for an M9 to use in a tactical situation?

In a tactical situation, the proper reload procedure for an M9 involves first maintaining situational awareness and ensuring the weapon is pointed in a safe direction. When the magazine is empty, press the magazine release button to drop the spent magazine and grasp a fresh magazine with your support hand. Insert the new magazine into the magazine well with a firm push, then perform a quick visual and tactile check to ensure it is seated properly. Finally, rack the slide to chamber a round and regain your focus on the target.
