I finally finished fitting the arched mainspring housing for my 1911 yesterday. I did a cold reblue last night to clean up the shiny spots on the housing. Everything went back together smoothly this morning. Everything works, or as near as I can tell without taking it to the range. I'd rather not have learned how to detail strip the receiver of a 1911 the hard way though.
I'd still like to change the sights, but after taking over a month to get the gun back into working condition, I'm in no hurry to take it out of action again.
