I've had a Mark IV Hunter for a week and cleaned it three times now and get a giggle out of the fantastically easy takedown every time....not an Anderson Cooper giggle, but at least a chagrined chuckle or two. A chuckle because I think of the first time I disassembled a Mark III and had to bring it to a friend to put back together. Another chuckle when I think of the entire day that I set aside with a Mark III and a 22/45 just to repeatedly disassemble and reassemble until I could do each smoothly and in under an hour. Chagrined because I can't imagine why Ruger didn't redesign this thing for easier cleaning way before introducing the Mark II, let alone the Mark III. If they'd done this years ago, there would be no Beretta Neos, maybe no Buckmark, and the Colts and Hi Standards would have been discontinued earlier. Ruger would rule the 22lr pistol autoloader market. Tremendous finishing quality to the Mark IV, and more accurate than I am. I may switch out the rear sight someday for a target sight, but for now I've been content just to switch the Hi-Viz front to a white dot so that it blends with the rear marker. The trigger is okay for now, but the simple trigger pivot pin, or whatever it is called, is just begging for me to switch to a decent drop-in trigger whenever one is available. Kudos Ruger.
