Thanks you for your kind words.
The second side safety is an original Mauser mechanism, not one of our own systems.
If you look carefully at the third picture you will notice that when the safety is pulled to the rear it will block the sear and bolt movement.
The trouble isn't in making the safety itself but in the machining of the rear portion of the receiver.
Notice also that the safety benefits from some sort of stalking button that must be depressed in order to slide it in forward position: safety off.
