STEP 1: When you reach the point at which the slide locks back after the final shot, press the magazine release button. This can be done with the shooting-hand thumb (right-handers) or the trigger finger for southpaws. Simultaneously tilt the magazine well 45 degrees inward to the side that the new magazine will arrive from. If the gun is a drop-free magazine design, let it drop. If not, or if it instead uses a European-style release on the heel of the pistol, the support hand must linger to strip the magazine from the gun.
