Khunhausen book is good, no doubt. The place I learned most of my 1911 skills is
from a book by an old AF 1911 armorer from Oklahoma who self published it in the
pre-word processor days. Hand drawn, somewhat crude sketches and literally typed
on a typewriter, then reproduced. The best part, although the book is excellent, was
that I could see him at a gun show two or four times a year and ask questions. He
would answer them and help. About 15 years ago he missed two or three gun shows
and when I finally saw him again, I told him I missed talking to him. He said he had
some health problems that had kept him from traveling. We chatted a bit and I
told him how much I enjoyed and valued his book. I never saw him again after that.
I suspect he has passed on, sad to say.
But Khunhausen is real good. I can show you how to do a proper trigger job, if
you are interested. I have his other 1911 book, and Garand/M14 book, Mauser
bolt actions, Colt revolvers and S&W revolvers. All good stuff, although there
are alternate ways to do some of the things he shows, and sometimes better
ways. I learned more about S&W revolvers from a friend.
