This is a good and necessary change. The laborious takedown of the Mk pistols has made them seem dated in today's .22 market.
I think the S&W Victory had a lot to do with pushing Ruger to make this shift.
Will wait for a Mk IV 22/45 version to appear - preferably with a factory-included Pic rail on top.
PS: Note that the Mk IV "Hunter" model has the imprecise V-notch rear sight -- always a terrible idea for a .22. I can't tell whether the fiber optic front sight on the Hunter has a square or rounded face; if rounded, they really couldn't have done much more to impair the sights on that pistol. Those setups should just disappear. The "Target" has real sights and would be the way to go.
