+1 on the Jerry Miculek video. Vew it a couple times and you will have no problem. A rebound slide tool will help, or you can make one by bending and grinding an old flat tip screwdriver to fit. Once everything is out, a soak in acetone can cut the gunk of the parts. You can also use acetone in the frame. An old toothbrush or a dedicated gun cleaning brush is helpful. Then some compressed air to blow it all out. If you do use the acetone, be sure to wipe all down with a CLP or good oil as it will remove all the lubrication from it. I use Break Free and have for years.
