Gently push the take the down lever on left side upward while pushing in on the end of the take down pin on the right side. The take down lever will slide right out. Hold the slide ifirmly in the rearward position (it is under spring tension) while releasing the safety (push it down). Maintain a grip on the slide as you allow it to move forward off the frame. Once the spring tension is released, it will come right off. Hold the slide/barrel assembly upside down and pointing away from you. Grip and push the recoil guide rod against the tension of the spring around it. Lift it out of its seat on the barrel lug and set aside. Grasp the barrel lug, pull it up and slightly forward, then remove it from the slide. Assembly is the reverse. The Hi-power is one of the easiest semi-autos to field strip that exists.
