How do you simply take apart a jennings firearm .380 model 48 auto?

Remove the magazine from the pistol. Pull back the slide, and check to be SURE that there is no ammunition in the gun. Check it again. With an EMPTY gun, point in a safe direction, release safety, pull trigger to uncock the pistol. Holding it pointing away from you, use a blunt object (ball pont pen) to push in the take-down button on the rear of the slide. While holding in buttom raise rear of slide, slide forward off the barrel and frame. Carefully release pressure on take down button, removing it, spring, and firing pin from channel. STOP. That is as far as you should go for normal maintenance and cleaning.
