So back to the disassembling...
If you don't have the owner manuals the first thing I would do is go to the mfg's site and download/print out copies.They will cover how to disassembly,care/cleaning step by step.Good luck!
For me YouTube has been a God send. It is not unusual to find multiple videos that a cover disassembly/assembly of popular firearms. Ruger's Tech Tip guy may be kind of dorky but the videos are very helpful. I have downloaded many videos and keep them as part of a reference library.
Be sure to have the manuals and start there. But also check out YouTube, Google videos, etc.
Good luck!
