An interesting way to prevent sliding wear, also on lighter alloys is used in several car engine designs.
The sliding point is covered with tiny silica pieces. The surface is etched slightly to bring the silica pieces to the surface, providing a glasshard sliding area.
I also wonder how a much less steep, longer ramp would hold out? The main objective of the ramp is to get the toggle joint above a certain level and this can be done with a much less steep angle as used on the traditional luger design. A less steep ramp would be able to withstand the forces applied upon it much better?
It would certainly create an interesting gun design
