This discussion is a good one. I believe it's exactly what Ken wanted; get the juices flowing and discussing pros and cons of potential changes. Ken did say: "I have wanted to re make the Lefever shotgun but better than the original."
I'm not an advocate of intercepting sears for this project, but this discussion could reveal a ingenious safety feature that would be invisible to the user and easily incorporated, yet provide better safety than a conventional sear or trigger blocking safety. Frankly, I don't know what type of safety the Lefever has.
