For all you guys and gals who took the time to learn to disassemble/reassemble your Mark whatever's....good for you.
It's a basic concept of customer service that when a number of people tell you that your product has a problem, then you should quit trying to tell them why they're wrong and FIX THE PROBLEM.
Nice to know that eventually I'd get it right if I kept trying, but I've got several other guns from other manufacturers that I took down correctly the first time; some intuitively. The point is that Ruger's take some effort. A Beretta 87, another 22 plinker for instance, doesn't take a day to learn.
And racky; I got the 1911 by myself...took 2 attempts to memorize it. I've never gotten there again with my Ruger, primarily because I had to get someone else to reassemble it every time.
