I think this discussion is fascinating. I certainly trust Miller's opinion regarding the hammer block. Would I want / appreciate a safety? Certainly I would.

I have a simple question. Who is going to engineer this?

Ken is a very talented engraver. Steve Earle is a very talented machinist who is a master with the current technology. Glen Flewless, who will be fitting the barrels is also a talented master. Steve needs to be handed a working action or CAD drawings to machine any changes into the action. Who is going to supply those?
