I have laid awake at night thinking on those very same requirments and modifications! Biggest hold up is an appropiate rear sight that is adjustible, and also ergonomic so as to not hurt my front paw??? It is why the Navy type sight is ski ramped, it protects the sight, and also your hand.. The trigger pull could be improved, the fit of the receiver to frame would need to be perfect, and also the firing pin to the inside of the breechblock would need to be tight tolerence as well... as does the breechblock to receiver. Trigger overtravel and take up screws would be easy enough? You would have to try a crap load of parts to meet all the parameters necessary? It's getting to be a bit late in the game for me, but perhaps some young whipper snapper could pick up the ball and run with it?... Best to all, til....lat'r....GT
