Fieldstripping the H9 is simple. Clear the magazine and lock the slide to the rear. Inspect the chamber to be certain it isn’t loaded. The takedown lever is pressed inwards right to left and rotated. Then work the slide from the rear to the front and the slide is removed from the frame. (The trigger must be pulled to remove the slide.) The barrel is easily removed from the slide by pressing it downwards. The recoil spring stays in the frame.
