Detail Stripping the 1912 M1911
I soaked the rust with Ballistol, and scraped at it with a copper penny. I have, over the years, adopted the Lincoln cent for a scraping tool on guns. The copper is softer than the metal, and I have yet to scratch a finish with old Honest Abe. The grips were quite stuck, but with a little persuasion, they let go of the bushings.
As I dived deeper into the detail strip and evaluation, I saw that this pistol did indeed have the original finish. The two toned look on the grip frame is actually two different directions of polishing applied at the factory. This two toned appearance is quickly altered in a M1911 has been refinished.
I lubricated the pistol like I do all my 1911s, grease on the slide rails and sear, oil on the pivoting parts. When I was done, the pistol was glistening with Ballistol, inside and out. I will let the Ballistol remain on the gun, not wiping it off, for several days. Hopefully it will soak into the remaining oxidation and help loosen it from the finish.
