So, since this board doesn't have a good set of instructions on how to clean the lower part of your Steyr M-A1 (9/40/357), I sat down with my camera and made some real nice ones for you to use. Enjoy! Disassembly of M-A1 frame Assembly of M-A1 frame Disassembly/Assembly of M-A1 slide After reviewing my process, I'm going to make some changes to the documents. I found another way to remove the extractor that does not damage the slide, but potentially could launch the spring and pin. When updated, I'll let you know it's done. For now, these work.
