Warning on reassembly
If that strut is not in the right place the pistol WILL go back together again but, the bolt will not move rearward and another disassembly will be dang near impossible for you to fix it without a gunsmith to help you out.
BTW I did find a page for Mark III 22/45 Takedown but, something is wrong with the site. It keep jamming my 'puter when I try to select all & copy the text.
And when I try to link to the page it shows as a dead link on the forum. Very strange.
