I have to wonder, is the difficulty of disassembly intentional? Now, I have posted several times that I can disassemble and re assemble them no problem, but it certainly isn't foolproof, and there are certain things that need to position just so.
So, if we say this was intentional, then Bill Ruger was just a jerk who didn't want people to be able to get inside his guns. On the other hand, if we say it was just coincidental, then Bill Ruger was a pretty mediocre engineer and gun designer. Either statement will have the Ruger Collector's Association firing up the tar pots and plucking chickens, but I do just have to wonder. I was cleaning two MK IIs last night, and it just struck me how perfect the length of that hammer strut is to hang right up on that cross pin. Almost perfectly engineered to cause problems.
Excuse me, now I need to go into hiding...
