Congrats on the purchase, I recently also picked up a LE trade in 4006 sweet pistol. I sent S&W an email requesting a manual and about 5-6 weeks later I received one in the mail no charge. It explains how to breakdown the weapon. Basically you pull back the slide aprox. 3/4 to 1 inch and at the same time press down on the pin in the countersunk hole on the right side above the trigger. I found taking a bullet and pressing it in the countersunk hole worked best. You may have to move the slide back and forth a little but you'll feel it " catch " when you have found the spot. Then you just slowly push the slide forward and off the weapon. Sounds hard until you've done it 2-3 times and then it's apiece of cake. Hope this helps.
