At that level of disassembly, pulling the hammer and pushing the pin that holds the disconnector is maybe 10 minutes tops. I polished everything while I was in there, even things that would be felt on the DA pull like the hammer strut. If I ever go back(doubtful), it's already done. Even with the CZC comp hammer I have a little creep, no way I would have liked it with an OEM hammer. JRR, the Shadow doesn't have a fpb, so no worries there.
