Ruger Mark pistols? Really? Sure, it's harder than a Glock and would be a bit baffling wothout a manual, but in this age of the internet, Ruger has it online. Follow the directions, it's a piece of cake.
Now the mag disconnect on the MkIII.... I got rid of that.
Most complicated I've detail stripped is a CZ52 after my g/f dropped hers in the sand at the range. Sure, field stripping it is simple, but a full strip down to the frame reveals waaaay more parts than needed for a single action autoloader. I'll stick to my Tokarev, thanks! The Yugo models can be detail stripped with the exception of the extractor using no tools.
