PK did his mod on my 27 a1 several years ago where he added a full auto lever that when in the auto position acts as a bolt hold open. Since then it has been in my safe and I lost PK’s instruction on how his mod changed the disassembly procedure. I seem to recall that his mod no longer requires use of a flathead screwdriver for disassembly, but I can’t recall anything else. Can anyone help me with disassembly procedure after this PK modification?
