I have disassembled my slide to clean the extractor channel and inspect the firing pin. And I can field strip my 1911 in my sleep. But I have not yet disassembled the bottom end (frame). Looking a the Wilson Combat 1911 disassembly video is very helpful. My Specialist has an ambi-safety and that part looks a little tricky. I’m not sure what keeps the 2 halves joined. Seems as if it may just be interference fit? If I wanted to just inspect the sear and disconnector I’m assuming you can’t remove the pin that they rotate on without removing the ambi-safety? Any advice would be appreciated. What is the most likely thing to go wrong? Also it seems if most smiths wind up tapping on the safety lever to help loosen it. Is it easy to scratch the finish if prying up with a sharp tool like a flat (thin) screwdriver? The WC guy used a thin piece of paper to protect the finish. Anyway, for anyone that learned something the hard way, I would appreciate your knowledge. The mainspring housing, spring cap and magwell looks straightforward. Thanks in advance.
