Like all the ruger 22's mk's, taking it apart is no big deal.
Putting it back together sometimes can be a challenge.
But it is a great gun. Have several variation's.
But i was looking for, at least in my case a combat style 22 pistol. The M&P seem's to fit the bill.
I think i have ruled out the Sig or the GSG. Still a little too much going on with those gun's.
But i will get a 22 conversion kit for one of my 1911's.
