Easiest one I own is a High Standard Sport King. Drop the magazine and push one plunger.
Ruger Mark II and Ruger .22/45,,,,and no, I'm not kidding,,,are really easy to field strip, clean and reassemble once you get the hang of it. One take down lever to pull, and it pretty much falls out into a frame, bolt, bolt stop and barrel/reciever. Put it together in reverse while twisting and turning it the right way and it goes back together.
I admit I had some trouble at first like most others. After doing it 10 or 20 times, I can strip and reassemble it faster than a HP, 1911 or CZ75b. Compared to a Buckmark or a S&*, 22a/22s, it's a no brainer.
