If you find commercially available screwdrivers to fit ANY of the screws, other than the buttplate and stock screws, please be a kind soul and post the info here. Fortunately I have a good source of large broken old hacksaw blades and a grinder. When I ground screwdrivers they always got too soft, and I had no luck re-tempering. With the saw blades, just dip them in oil when hot and go.
When it comes to these screws on S x S guns, I would gladly forego the aesthetics for a good allen head or torx socket.
