There isn't a very good video for removing the slide lock and slide lock spring. You can use the Glock tool(3/32 inch punch) to depress the spring while you remove the slide lock, but removing the spring ideally you need something thinner like a 1/16 inch punch or even thinner. To remove the slide lock you push the spring down closest to the slide lock, while holding the spring down you tilt the frame to the side and wiggle the slide lock around until it falls out. Then you put the thin punch under the slide lock spring from the rear of the frame, move the tip of the punch up to where the spring goes into the frame, and gently incrementally work the spring upward. Take note of which way the spring goes back in. When putting the slide lock back in, it should be positioned like this: http://oi55.tinypic.com/2zxw6s1.jpg
On the following page are some Glock Armorer's Manuals, just scroll down to the "G" section. I learned from the Update Manual and 2009 Manual. The 2009 Manual has a few pages missing, but that info can be found in the Update Manual as well.
