The Ruger MK series pistols need no tools to disassemble nor reassemble. Well maybe a paper clip to ease pulling out the takedown lever on the back of the grip.
If you can read the manual, and actually have it with you when you take apart the psitol for cleaning then you can easily do it. There are also a plethora of Youtube vids now available to walk you through it, so there really are no excuses.
