This is my first post here and just wanted to say thanks for this document. Have had my MK9 for about 5 years now and for the first time stripped the slide. Couldn't have done it without these instructions.
FWIW, the slide wasn't all that dirty inside. The one spot there was alot of gunk was under the striker block and in the spring. Didn't seem to affect function but it there was alot of "sludge" in there....
