Denizen,
Concerning your post #44, I think your question is valid. There is more to making this work than just the hammer. To turn the 07/09 series into a top performer, the disconnector and lifter must also be engineered to work in concert with the revised hammer. This means basically half of the lock work will be re-engineered.
Not easy, and I want to get this right the first time. But we are very, very close.
