As far as maintenance goes, all I do is clean my 1911's. Somebody is misstating things immensely, and it ain't me. I used to shoot in the basement of the National Guard armory in Lincoln and the range beater 1911's ran and ran and ran. Parts were randomly mixed together when the guns were group cleaned in the parts washer.
Too many here hypothesize without foundation. Not one of those guns had anything but parts that dropped in without fitting. My suggestion is to ask about everyone's experience before you take the word of "experts." Too often these types have an agenda that distorts reality.
As here.
