There are pictures of the slide parts and the order and care needed for taking it apart and putting it back together. A "C" clamp is easy to make and each Kahr requires a slightly different length, but coat hangers are cheap. See ripley16's picture on post #3 in that same thread.
After removing the back plate, I use a straightened paper clip to push the pin, spring and rear pin out the back. The extractor just rotates inward, forward, and free. Then you can depress the safety block, and then remove the striker spring, striker and the spring rest in the striker. Then remove the safety block and its tiny spring.
For re-assembly, the safety block and spring goes in before the striker and extractor assemblies. Put the striker pin retainer in the striker and the spring in the striker and put those into the striker channel. The safety block needs to be pressed in for the striker to go by it.
The front pin in the extractor train has to be oriented correctly towards the front, and extractor can be taped in place so that you can position the correctly oriented front pin, the spring , and then the rear pin before compressing them with the "c" clamp that you made from a coat hanger.
The smallest jeweler screwdriver is the best for depressing the rear pin to remove and replace the back plate. it's thin and strong enough for the job of getting past the half-moon hole to depress the rear pin.
A clear plastic bag can be helpful to retain the parts. Just remember that the striker spring and the extractor assembly can go flying as the rear plate is slid off. The "C" clamp can keep the striker assembly in place... but remember not to let it loose.
