good to knowLugs on the frames are different between 22/45 and Mark 2s. It's not much but it's enough. Don't remember which is which, but one wont go, the other goes loose. Will edit after I dig out the Rugers. Mark 2 goes on 22/45 frame loose. 22/45 will not go on Mark 2. Turns out there is a lot of difference in the height of the lug on the 22/45.
